User-defined commands are especially convenient for complex expressions.
When you are for example dealing in a document with quadratic equations,
the same solution type occurs several times.
The general form of a quadratic equation is
\begin_inset Formula \[
0=\lambda^{2}+p\lambda+q\]
\end_inset
The general form of the solution is
\begin_inset Formula \[
\lambda_{1,2}=-\frac{p}{2}\pm\sqrt{\frac{p²}{4}-q}\]
\end_inset
\end_layout
\begin_layout Standard
To define a command for the solution formula where only the three parameters
\begin_inset Formula $\lambda$
\end_inset
,
\begin_inset Formula $p$
\end_inset
, and
\begin_inset Formula $q$
\end_inset
need to be specified and the index of
\begin_inset Formula $\lambda$
\end_inset
can be given optionally, the LaTeX-preamble line is
\begin_inset Newline newline

\begin_layout Standard
To create with this the solution formula, the command

qG{
\backslash

\begin_inset Formula $\to$
\end_inset
\backslash
{p
\begin_inset Formula $\to$
\end_inset
\backslash
{q
\series default
is inserted to a formula
\series bold
.
\end_layout
\begin_layout Standard
The definition of the new command is unintuitive because one has to know
the schemes of all used LaTeX commands, e.
\begin_inset space \thinspace{}
\end_inset
g.
\begin_inset space \space{}
\end_inset
that a fraction is inserted in LaTeX as
\series bold
\backslash
frac{numerator}{denominator}
\series default
.
Furthermore one can easily forget a brace in the definition and cannot
see in LyX what the new command is doing.
To avoid these problems LyX offers the possibility to use math macros instead
of the command
\series bold
\backslash
newcommand
\series default
.
\end_layout
\begin_layout Standard
A math macro is created by using the menu
\family sans
Insert\SpecialChar \menuseparator
Math\SpecialChar \menuseparator
Macro
\family default
or the toolbar button
\begin_inset Graphics
filename ../images/math-macro_newmacroname_newcommand.png
scale 85
\end_inset
.
The math macro toolbar appears together with the following box where the
macro is defined:
\begin_inset Newline newline
\end_inset
\begin_inset space \hspace*{\fill}
\end_inset
\begin_inset Graphics

\begin_inset FormulaMacro
\newcommand{\qG}[4][1,\,2]{#2_{#1}=-\frac{#3}{2}\pm\sqrt{\frac{#3^{2}}{4}-#4}}
\end_inset
\backslash
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
\backslash
#1
\series default
or by using the macro toolbar button
\begin_inset Graphics
filename ../images/math-macro-add-param.png
scale 85
\end_inset
.
Argument placeholders are displayed red.
Maximum 9 arguments are possible.
Optional arguments are created with the toolbar button
\begin_inset Graphics
filename ../images/math-macro-add-optional-param.png
scale 85
\end_inset
.
The first non-optional argument can be transformed to an optional one with
the toolbar button
\begin_inset Graphics
filename ../images/math-macro-make-optional.png
scale 85
\end_inset
.
In the second blue box the appearance of the macro in LyX can be defined.
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 LyX, leading to a better overview.
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
View\SpecialChar \menuseparator
(Un)fold
\begin_inset space ~
\end_inset
Math

\end_layout
\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 LyX like this:
\begin_inset Newline newline
\end_inset
\begin_inset space \hspace*{\fill}
\end_inset
\begin_inset Graphics
filename clipart/macrouse.png
lyxscale 75
scale 75
\end_inset
\begin_inset space \hspace*{\fill}
\end_inset
\begin_inset Newline newline
\end_inset
Here is our macro example with the arguments
\begin_inset Formula $x$
\end_inset
,
\begin_inset Formula $\ln(x)$
\end_inset
, and
\begin_inset Formula $B$
\end_inset
:
\end_layout
\begin_layout Standard
\begin_inset Formula \[
\qG x{\ln(x)}B\]
\end_inset
\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 LaTeX-preamble, therefore macros can only
be used in formulas that are in the document below the macro definition
box.
\end_layout
\begin_layout Standard
Math macros can also be directly be 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 LyX as normal text, highlighting it completely and using then the shortcut
\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
LaTeX errors.
\end_layout
\begin_layout Standard
Math macros currently yet have the problem that further formulas in macro
definitions are handled wrongly.
Therefore the example
\series bold
\backslash
fb
\series default
from
\begin_inset CommandInset ref
LatexCommand ref
reference "sub:The-Command-newcommand"
\end_inset
cannot be created as macro.

Außerdem kann man leicht eine geschweifte Klammer vergessen und man kann

Um diesen Problemen aus dem Weg zu gehen, gibt es in LyX die Möglichkeit
Mathe-Makros statt den Befehl

newmacroname ist der voreingestellte Makroname, der auf etwas sinnvolles

In das erste blaue Kästchen gibt man die gewünschte Formel ein.

Argumentplatzhalter werden rot dargestellt.
Es sind maximal 9 Argumente möglich.

Mit dem Werkzeugleistenknopf

kann das erste nicht-optionale Argument in ein optionales verwandelt werden.
Im zweiten Kästchen kann man definieren wie das Makro in LyX angezeigt

Normalerweise will man es so sehen, wie es definiert wurde, wozu man das

Für das Makro werden dann in LyX nur die Argumente mit dem davor stehenden

Im Ausdruck erscheint die Formel so, wie sie im ersten Kästchen definiert

Der

\begin_layout Standard
Mathe-Makros können auch direkt aus einem
