Introduction
\end_layout
\begin_layout Standard
This document explains \SpecialChar LyX
's math features and is furthermore a collection
of \SpecialChar LaTeX
-commands used for mathematical characters and constructs.
2013-10-05 14:59:04 +00:00
The explanations are designed for the usage of commands.
It is therefore required that you have read the section
\family typewriter
Mathematical
\begin_inset space ~
\end_inset
Formulas
\family default
of the User's Guide.
\end_layout
\begin_layout Standard
Most of the characters and many constructs explained in this manual are
also accessible via the menu

or the
\family sans

\series bold

toolbar

.
But everybody who has to write lots of formulas will notice that it is
much faster to use commands instead of the math toolbar.
Therefore this manual is focused on commands but also mentions the correspondin
g toolbar buttons when available.
\end_layout
\begin_layout Standard
If not specially mentioned the commands are only available within formulas.
To be able to use all commands explained in this document, the option

Command Scheme
\end_layout
\begin_layout Standard
Most of the \SpecialChar LaTeX
-commands for math constructs have the following scheme:
2013-10-05 14:59:04 +00:00
\end_layout
\begin_layout Standard
\series bold
\backslash
commandname[optional
\series default
\series bold
argument]{required
\series default
\series bold
argument}
\end_layout
\begin_layout Standard
A command always starts with a backslash
\begin_inset Quotes gld
\end_inset
\series bold
\backslash
\series default
\begin_inset Quotes grd
\end_inset
.
To omit optional arguments, also omit the associated brackets.
The braces around the required arguments are named in this document as
\SpecialChar TeX
braces

\begin_layout Plain Layout
T@\SpecialChar TeX
-braces
2013-10-05 14:59:04 +00:00
\end_layout
\end_inset
.
If you add in a formula a left brace to a command name, \SpecialChar LyX
automatically
creates a \SpecialChar TeX
brace.
In all other cases \SpecialChar TeX
braces are created in formulas with the command
2013-10-05 14:59:04 +00:00
\series bold
\backslash
{
\series default
.
\SpecialChar TeX
braces appear red in \SpecialChar LyX
, in contrary to normal braces which appear blue.
In \SpecialChar TeX
mode no command is needed to get \SpecialChar TeX
braces.
\SpecialChar TeX
braces don't appear in the output.
2013-10-05 14:59:04 +00:00
\end_layout
\begin_layout Standard
When commands without arguments, like commands for symbols are entered in
\SpecialChar TeX
mode, a space character must
2013-10-05 14:59:04 +00:00
\emph on
always
\emph default
be behind the command to end it.
This space doesn't appear in the output.
When the space should appear in the output, the space must be followed
by a protected space in normal text.
\end_layout
\begin_layout Standard
A protected space is inserted with
\begin_inset Info
type "shortcuts"
arg "command-alternatives space-insert protected ; math-space"
\end_inset

It is possible to specify the alignment of the numerator.
The command
\series bold

to right-align it.
\series bold

These fractions demonstrate the different alignments:

Specially for matrices there are ellipses that span over several columns.
They are created with the command
\series bold
\backslash
hdotsfor
\series default
\begin_inset Index idx
status collapsed
\begin_layout Plain Layout
Commands ! H !
\backslash
hdotsfor
\end_layout
\end_inset
, that has the following scheme:
\end_layout
\begin_layout Standard
\series bold
\backslash
hdotsfor[distance]{number of columns}
\end_layout
\begin_layout Standard
The number of columns specifies how many columns should be spanned.
Distance is a factor for the distance between the dots.
\end_layout
\begin_layout Standard
In the following matrix the command
\series bold
\backslash
hdotsfor[2]{4}
\series default
was inserted in the first box of the second line, to get an ellipsis with
a dot distance twice as long as with the command
\series bold
\backslash
dots
\series default
:
\begin_inset Formula
\[
\left(\begin{array}{cccc}
A & B & C & D\\
\hdotsfor[2]{4}\\
q & w & e & r
\end{array}\right)
\]
\end_inset
Note that the matrix fields that should be spanned must be empty, otherwise
you get \SpecialChar LaTeX
-errors.

In the matrix dialog you can specify the number of columns and rows, the
alignment and the decoration.
The vertical alignment is only of importance for matrices in inline formulas:
\end_layout
\begin_layout Standard
The first matrix is top
\begin_inset Formula $\begin{array}[t]{cccc}
A & D & G & J\\
B & E & H & K\\
C & F & I & L
\end{array}$
\end_inset
, the second middle
\begin_inset Formula $\begin{array}{cccc}
A & D & G & J\\
B & E & H & K\\
C & F & I & L
\end{array}$
\end_inset
and the third bottom
\begin_inset Formula $\begin{array}[b]{cccc}
A & D & G & J\\
B & E & H & K\\
C & F & I & L
\end{array}$
\end_inset
aligned.
\end_layout
\begin_layout Standard
The horizontal alignment specifies how the column entries should be aligned.
It is set by entering a letter for every column.
\emph on
l
\emph default
denotes left aligned,
\emph on
c
\emph default
centered and
\emph on
r
\emph default
right aligned.
To create for example a 4
\series bold

\end_inset
matrix where the first column is left aligned, the second and third are
centered and the last one is right aligned, one enters for the horizontal
alignment
\series bold

Normally in a matrix all columns are centered, therefore the default for
every column is a
\series bold

\series default
.

When brackets should overlap each other, multiline formulas, as described
in
2013-10-05 14:59:04 +00:00
\begin_inset CommandInset ref
LatexCommand ref
reference "sec:Multiline-Formulas"
\end_inset
, must be used:
\begin_inset Formula
\begin{eqnarray*}
A & = & \underbrace{gggg+bbqq}_{r}+\:dddd\\
2013-10-05 14:59:04 +00:00
& & \hphantom{gggg+\:}\underbrace{\hphantom{bbqq+dddd}}_{s}
\end{eqnarray*}
\end_inset
In the first row the formula is inserted together with the first brace.
It is hereby important that the space command

\end_layout
\end_inset
\series bold
\backslash

\series default
is inserted before the first
\begin_inset Formula $d$
\end_inset
, because the brace that ends behind the
\begin_inset Formula $q$
\end_inset
prevents that the following
\begin_inset Quotes eld
\end_inset

\begin_inset Quotes erd
\end_inset
is surrounded by space.
\begin_inset Foot

\begin_layout Plain Layout
because a bracket is not handled as a character, see

LatexCommand ref
reference "subsec:Binary-Operators"
2013-10-05 14:59:04 +00:00
\end_inset
\end_layout
\end_inset
In the second row the second brace is inserted.
As it should begin before the
\begin_inset Formula $b$
\end_inset
, first the command
\series bold
\backslash
hphantom{gggg+
\backslash

\end_inset
This space is needed because the
\begin_inset Quotes eld
\end_inset

\begin_inset Quotes erd

is also surrounded by space in the formula.
The brace is placed under the command
\series bold
\backslash

\end_layout
\begin_layout Standard
It gets more complicated when brackets overlap each other above and under
the formula, like in the following example:

The first formula row is the same as the second row of the previous example,
with the difference that the brace is above.
The second row contains the formula together with the second brace.
To avoid that there is space between the upper brace in the first row and
the formula, the row spacing needs to be reduced.
This is not easily possible due to a bug in \SpecialChar LyX
.

Another advantage to

\series default
is that umlauts can directly be converted to mathematical text because
the accent commands above are
\emph on

To convert an accented character to mathematical text, only the character
under the accent may be converted.
This applies also for all other conversions, e.
\begin_inset space \thinspace{}

g.
\begin_inset space \space{}
\end_inset
to italic or bold.

In the last example the available space is given by the longest column entry
of the table.
In an inline formula the space depends on the length of the line in which
\series bold
\backslash
hfill
\series default
is inserted.
Thus, when the line uses the full width, no space will be created.
\series bold
\backslash
hfill
\series default
only has an effect on displayed formulas when the formula style
\series bold
Indented
\series default
is used.

Instead of

also the color space

\series bold

denotes

The operators are called big because they are bigger than the sometimes
equal looking binary operators.
All big operators can have limits as described in the next subsection.
\end_layout
\begin_layout Standard
For all integral operators there is a second version available, ending in
\series bold
op

etc..
These operators are different from
\series bold

\begin_layout Standard
The letter
\emph on

\emph default
in an integral is an operator, that therefore has to be set upright.
This is done by highlighting the
\emph on
d
\emph default
and using the keyboard shortcut

\end_inset
\begin_inset Foot

\end_inset
\end_layout
\end_inset
.
Finally the smallest space is inserted before the
\emph on
d
\emph default
, as this is usual for operators.

\begin_layout Standard
Limits of inline formulas are set right beside the operator.
Limits in displayed formulas are set above or below the operator, except
for integral limits.
\end_layout
\begin_layout Standard
To force that the limits are set beside the operator, the cursor is set
directly behind the operator and the limits type is changed with the menu
\family sans
Edit\SpecialChar menuseparator
Math\SpecialChar menuseparator
2013-10-05 14:59:04 +00:00
Change Limits Type
\family default
to
\family sans
\series bold
Inline
\family default
\series default
(shortcut
\begin_inset Info
type "shortcut"
arg "math-limits"
\end_inset
).
An example:
\end_layout
\begin_layout Standard
The default limits type is this:
\begin_inset Formula
\[
\sum_{x=0}^{\infty}\frac{1}{x^{2}}
\]
\end_inset
This is how it looks when the limits type was changed to
\family sans
\series bold
Inline
\family default
\series default
:
\begin_inset Formula
\[
\sum\nolimits _{x=0}^{\infty}\frac{1}{x^{2}}
\]
\end_inset
For integrals, except those ending with
\series bold
op
\series default
like
\series bold
\backslash
intop
\series default
,
\series bold
\backslash
ointop
\series default
etc., the limits are by default set beside the operator.
But for multiple integrals the limits are often set below the operator.
In the following example the limits type was therefore set to
\series bold
Display
\series default
and so set below the integrals:
\begin_inset Formula
\begin{equation}
\iiint\limits _{V}X\,\mathrm{d}V=U\label{eq:VolInt}
\end{equation}
\end_inset
\end_layout
\begin_layout Standard
\begin_inset VSpace medskip
\end_inset
To specify conditions for limits, the commands
\series bold
\backslash
subarray
\series default
\begin_inset Index idx
status collapsed
\begin_layout Plain Layout
Commands ! S !
\backslash
subarray
\end_layout
\end_inset

\backslash
substack
\series default
\begin_inset Index idx
status collapsed
\begin_layout Plain Layout
Commands ! S !
\backslash
substack
\end_layout
\end_inset
are used.
To create for example this expression
\begin_inset Formula
\begin{equation}
\sum_{\begin{subarray}{c}
0<k<1000\\
\\
k\,\in\,\mathbb{N}
\end{subarray}}^{n}k^{-2}\label{eq:substack}
\end{equation}
\end_inset
\end_layout
\begin_layout Standard
the following has to be done:
\begin_inset Newline newline
\end_inset
First the command
\series bold
\backslash
sum
\series default
^
\series bold
n
\begin_inset space \textvisiblespace{}
2013-10-05 14:59:04 +00:00
\end_inset
_
\series default
is typed in.
One is now in a blue box under the summation operator and insert there
the command
\series bold
\backslash
subarray
\begin_inset space \textvisiblespace{}
2013-10-05 14:59:04 +00:00
\end_inset
\series default
.
The blue box is now within a purple box and now several lines can be written
among each other.
A new line is created by inserting a line break (
\begin_inset Info
type "shortcut"
arg "newline-insert newline"
\end_inset
).
When now
\begin_inset Newline newline
\end_inset
\series bold
0<k<1000 Ctrl+Return
\begin_inset Newline newline
\end_inset
\series default
is typed in, a new box appears below for the new line.
\end_layout
\begin_layout Standard
The alignment of the lines can be changed to left aligned with the
\family sans
table
\family default
\family sans

Like in formula

there can be too much space beside an operator, because the characters
following the operator are set beside the limits.

and inserts the operator with its limits into the braces.
Behind the brace one continues the formula:
2013-10-05 14:59:04 +00:00
\begin_inset Formula
\[
\smashoperator{\sum_{\begin{subarray}{c}

\]
\end_inset
\end_layout
\begin_layout Standard
It is possible to set the space of only one side of the operator to 0
\begin_inset space \thinspace{}
\end_inset
pt.
To do this write either
\series bold
[l]
\series default
or
\series bold
[r]
\series default
between
\series bold
\backslash
smashoperator
\series default
and its brace.
\series bold
l
\series default
stands for the left and
\series bold
r
\series default
for the right side of the operator.
Here is an example of the possible
\series bold
\backslash
smashoperator
\series default
forms:
\end_layout
\begin_layout Standard
\begin_inset Formula
\[
Y\smashoperator{\sum_{1\le i\le j\le n}^{n=3456}}X_{ij}=Y\smashoperator[l]{\sum_{1\le i\le j\le n}^{n=3456}}X_{ij}=Y\smashoperator[r]{\sum_{1\le i\le j\le n}^{n=3456}}X_{ij}

\]
\end_inset
\end_layout
\begin_layout Standard
\begin_inset VSpace bigskip

\end_layout
\begin_layout Standard
When several consecutive operators have limits the typesetting of the limits
looks often imperfect in the output, see this example:
\begin_inset Formula
\[
\text{a)}\lim_{n\to\infty}\max_{p\ge n}\quad\text{b)}\lim_{n\to\infty}\max_{p^{2}\ge n}\quad\text{c)}\lim_{n\to\infty}\sup_{p^{2}\ge nK}\quad\text{d)}\limsup_{n\to\infty}\max_{p\ge n}

\begin_layout Standard
The size produced by the commands depends on the document font size, which
corresponds to the command
\series bold
\backslash
normalsize
\series default
.
The other commands produce smaller or larger sizes than
\series bold
\backslash
normalsize
\series default
.
The font size can however not exceed a certain value.
Is for example the document font size 12
\begin_inset space \thinspace{}
\end_inset
pt, the command
\series bold
\backslash
Huge
\series default
switches to the same size as
\series bold
\backslash
huge
\series default
.
\end_layout
\begin_layout Standard
A size command is inserted in \SpecialChar TeX
mode before the formula and sets the size
2013-10-05 14:59:04 +00:00
for all following formula and text characters.
To switch back to the initial size, the command
\series bold

is inserted behind the formula in \SpecialChar TeX
mode.

That the big Greek letters appear upright is caused by a design bug when
\SpecialChar TeX
was developed.
2013-10-05 14:59:04 +00:00
To get correct italic big letters, begin every command with
\series bold
var
\series default
.
For example the command
\series bold
\backslash
varGamma
\series default
produces
\begin_inset Formula $\varGamma$
\end_inset
.
Another way is to load the package

To use a function that is not predefined, like for example the sign function
sgn(x), there are two possibilities:
\end_layout
\begin_layout Itemize
Define the function by inserting the following line to the \SpecialChar LaTeX

Now the new defined function can be called with the command

\series default
.
\end_layout
\begin_layout Itemize
Write the formula as usual, mark the formula name, in our example the letters
\emph on
sgn
\emph default
, and change it to mathematical text.
Finally, a space is inserted between prefactor and function.
\end_layout
\begin_layout Standard

\end_layout
\end_inset
\end_layout
\begin_layout Standard
The modulo-function is special, because it exists in four variants.
The variants in a displayed formula are:
\begin_inset Formula
\begin{align*}
\underline{\textrm{Command}\raisebox{-0.9mm}{}} & & \underline{\textrm{Result}}\\
\mathrm{a\backslash mod\textrm{␣}b} & & a\mod b\\
\mathrm{a\backslash pmod\textrm{␣}b} & & a\pmod b\\
\mathrm{a\backslash bmod\textrm{␣}b} & & a\bmod b\\
\mathrm{a\backslash pod\textrm{␣}b} & & a\pod b
2013-10-05 14:59:04 +00:00
\end{align*}
\end_inset
\end_layout
\begin_layout Standard
In an inline formula less space is set before the function names for all
variants.
By default the modulo-functions take only the first following character
into account.
To use more than one character, one has to put them into \SpecialChar TeX
braces:

\begin_inset Formula
\begin{align*}
\underline{\textrm{Command}\raisebox{-0.9mm}{}} & & \underline{\textrm{Result}}\\
\mathrm{a\backslash pod\textrm{␣}bcd} & & a\pod bcd\\
2013-10-05 14:59:04 +00:00

The first three have the same properties as the corresponding multiline
formula environments, but it is possible to set further formula parts beside
them.
An example:
\begin_inset Formula
\[

\Delta E\Delta t & \ge\frac{\hbar}{2}
\end{aligned}
\right\} \textrm{Uncertainty relations}

A purple box appears around the blue formula box where now columns and
lines can be added.
Outside the multiline environment other formula parts can be set, like
the brace.
\end_layout
\begin_layout Standard
The aligned environment is also suitable for long formulas whose lines are
horizontally aligned.
Using aligned in a displayed formula has the advantage that the formula
number is vertically centered behind the lines.

Sometimes formulas should be numbered in the following form:
\end_layout
\begin_layout Standard
\family typewriter

\begin_layout Standard
The formula number should start with every section with
\begin_inset Quotes eld

\end_layout
\begin_layout Standard
For this case there is the command

\begin_layout Standard
Counter denotes what kind of numbering is affected, sectioning denotes what
number is before the dot.
\end_layout

newmacroname is the default name of the macro that should be changed to
something sensible.
The wanted formula is inserted in the first blue box.
An argument placeholder is inserted with the command
\series bold
\backslash
#argumentnumber
\series default
, e.
\begin_inset space \thinspace{}
\end_inset
g
\begin_inset space \space{}
\end_inset
\series bold

or by using the macro toolbar button
\begin_inset Info
type "icon"
arg "math-macro-add-param"
2013-10-05 14:59:04 +00:00
\end_inset
.
Argument placeholders are displayed red.
A maximum of 9
\begin_inset space ~
\end_inset
arguments are possible.
Optional arguments are created with the toolbar button
\begin_inset Info
type "icon"
arg "math-macro-add-optional-param"
2013-10-05 14:59:04 +00:00
\end_inset
.
The first non-optional argument can be transformed to an optional one with
the toolbar button
\begin_inset Info
type "icon"
arg "math-macro-make-optional"
2013-10-05 14:59:04 +00:00
\end_inset
.
In the second blue box the appearance of the macro in \SpecialChar LyX
can be defined.
2013-10-05 14:59:04 +00:00
Normally you want to see it as it is defined, so the box is kept empty.
But when you have created a macro that needs lot of space on the screen,
you can insert in the box for example
\begin_inset Newline newline
\end_inset
\series bold
qG:
\backslash
#1
\series default
\series bold
,
\series default
\series bold
\backslash
#2
\series default
\series bold
,
\series default
\series bold
\backslash
#3,
\backslash
#4
\begin_inset Newline newline
\end_inset
\series default
For the macro only the arguments with the macro name in front of them will
then be displayed in \SpecialChar LyX
, leading to a better overview.
2013-10-05 14:59:04 +00:00
The formula appears in the output as defined in the first box.
\begin_inset Newline newline
\end_inset
The appearance of macros in formulas can furthermore be changed for single
macros by setting the cursor in the macro and using the menu
\family sans

\begin_layout Standard
To use a macro, the macro name is inserted as command to a formula, in our
case
\series bold
\backslash
qG
\series default
.
Our macro looks in \SpecialChar LyX
like this:
2013-10-05 14:59:04 +00:00
\begin_inset Newline newline
\end_inset
\begin_inset space \hspace*{\fill}

\begin_inset Formula $x$

\end_layout
\begin_layout Standard
A math macro is transformed internally to a
\series bold
\backslash
newcommand
\series default
command when exporting the document.
The created
\series bold
\backslash
newcommand
\series default
command is not placed in the \SpecialChar LaTeX
-preamble, therefore macros can only be used
in formulas that are in the document below the macro definition box.
2013-10-05 14:59:04 +00:00
\end_layout
\begin_layout Standard
Math macros can also be directly created from a
\series bold
\backslash
newcommand
\series default
command.
When writing for example the command
\series bold
\begin_inset Newline newline
\end_inset
\backslash
newcommand{
\backslash
larrow}[2]{
\backslash
xleftarrow[#2]{#1}}
\begin_inset Newline newline
\end_inset
\series default
in \SpecialChar LyX
as normal text, highlighting it completely and using then the shortcut
2013-10-05 14:59:04 +00:00
\family sans
Ctrl+M
\family default
, the command will be transformed to a math macro.
Using this method you need to be careful that the
\series bold
\backslash
newcommand
\series default
command is typed correctly, otherwise you get a faulty macro leading to
\SpecialChar LaTeX
errors.
2013-10-05 14:59:04 +00:00
\end_layout
\begin_layout Standard
Math macros currently have the problem that further formulas in macro definition
s are handled wrongly.
Therefore the example

\begin_inset CommandInset ref

Negative numbers often look ugly in formulas because the minus sign before
the number is set with the same length as the minus operator sign.
When writing the negative number in normal text, the minus sign appears
correctly.

Thus, the problem disappears when converting the minus sign to mathematical
text.

In \SpecialChar LaTeX
a comma inside a formula is used, according to the English convention,
2013-10-05 14:59:04 +00:00
as number group separator.
So there will be space added behind all commas in formulas.
\end_layout

To avoid this, the comma is highlighted and changed to mathematical text
(shortcut
