A simple equation can be numbered by two ways.
|
||||
The first is invocating the LyX command
|
||||
\family typewriter
|
||||
math-number
|
||||
\family default
|
||||
.
|
||||
The corresponding number
|
||||
\begin_float footnote
|
||||
\layout Standard
|
||||
|
||||
Or a
|
||||
\series bold
|
||||
#
|
||||
\series default
|
||||
mark since true numbering is not yet implemented.
|
||||
\end_float
|
||||
will appear after the right end of the equation.
|
||||
|
||||
\layout Standard
|
||||
|
||||
|
||||
\begin_inset Formula
|
||||
\begin{equation}
|
||||
x=y^{2}-3
|
||||
\end{equation}
|
||||
|
||||
\end_inset
|
||||
|
||||
|
||||
\layout Standard
|
||||
|
||||
Usually the equation number will be referred to in the document.
|
||||
It's safer to assign a label to the equation, instead of using a fixed
|
||||
number.
|
||||
Assigning a label to a non-numbered equation will make it numbered automaticall
|
||||
y.
|
||||
With the label
|
||||
\series bold
|
||||
planck
|
||||
\series default
|
||||
we can be refer to the equation (
|
||||
\begin_inset LatexCommand \ref{planck}
|
||||
|
||||
\end_inset
|
||||
|
||||
).
|

|
||||
|

|

\begin_inset Formula
|
||||
\begin{equation}

\layout Standard

In the case of an equation array, every line is sequentially numbered.
|
||||
It's possible to suppress the number for a single line with the command
|
||||
|
||||
\family typewriter
|
||||
math-nonumber
|
||||
\family default
|
||||
.
|
||||
The cursor must be at the row you want not to be numbered.
|
||||
\layout Standard
|
||||
|
||||
|
||||
\begin_inset Formula
|
||||
\begin{eqnarray}
|
||||
(x+y)(x-y) & = & x^{2}-xy+xy-y^{2}\nonumber \\
|
||||
& = & x^{2}-y^{2}
|
||||
\end{eqnarray}
|
||||
|
||||
\end_inset
|
||||
|
||||
|
||||
\layout Standard
|
||||
|
||||
It's possible to label more than one line.
|
||||
From the following array of equations we can refer to the equations (
|
||||
\begin_inset LatexCommand \ref{eq:gs1}
|
||||
|
||||
\end_inset
|
||||
|
||||
) and (
|
||||
\begin_inset LatexCommand \ref{eq:gs2}
|
||||
|
||||
\end_inset
|
||||
|
||||
) using their corresponding labels.
|
||||
\layout Standard
|
||||
|

|

\begin_inset Formula
|
||||
\begin{eqnarray}
|
||||
v_{k+1} & = & w_{k}+b_{1}\label{eq:gs1} \\

w_{k+1} & = & v_{k+1}+b_{2}

Nummeren en Etiketteren van vergelijkingen

|
||||
|
||||
Een eenvoudige vergelijking kan op twee manieren worden genummerd.
|
||||
De eerste is het aanroepen van de LyX opdracht
|
||||
\family typewriter
|
||||
math-number
|
||||
\family default
|
||||
.
|
||||
Het bijbehorende nummer
|
||||
\begin_float footnote
|
||||
\layout Standard
|
||||
|
||||
Of een
|
||||
\series bold
|
||||
#
|
||||
\series default
|
||||
teken omdat volledige nummering nog niet is geimplementeerd.
|
||||
\end_float
|
||||
zal aan het rechter einde van de vergelijking verschijnen.
|
||||
|
||||
\layout Standard
|
||||
|
||||
|
||||
\begin_inset Formula \begin{equation}
|
||||
x=y^{2}-3
|
||||
\end{equation}
|
||||
|
||||
\end_inset
|
||||
|
||||
|
||||
\layout Standard
|
||||
|
||||
Het is gebruikelijk om in het document naar het nummer van de vergelijking
|
||||
te verwijzen.
|
||||
Het is veiliger een etiket aan de vergelijking toe te wijzen, in plaats
|
||||
van een vast nummer.
|
||||
Het toewijzen van een label aan een niet genummerde vergelijking zal deze
|
||||
automatisch van een nummer voorzien.
|
||||
Met het label
|
||||
\series bold
|
||||
planck
|
||||
\series default
|
||||
kunnen we verwijzen naar de vergelijking (
|
||||
\begin_inset LatexCommand \ref{planck}
|
||||
|
||||
\end_inset
|
||||
|
||||
).
|
||||
\layout Standard
|
||||
|
||||
|
||||
\begin_inset Formula \begin{equation}
|
||||
\label{planck}
|
||||
E=hv
|
||||
\end{equation}
|
||||
|
||||
\end_inset
|
||||
|
||||
|
||||
\layout Standard
|
||||
|
||||
In het geval van een reeks vergelijkingen is iedere regel opeenvolgend genummerd.
|
||||
Het is mogelijk het nummer van een enkele regel te onderdrukken met de
|
||||
opdracht
|
||||
\family typewriter
|
||||
math-nonumber
|
||||
\family default
|
||||
.
|
||||
De cursor moet zich bevinden op de regel die je niet wilt voorzien van
|
||||
een nummer.
|
||||
\layout Standard
|
||||
|
||||
|
||||
\begin_inset Formula \begin{eqnarray}
|
||||
(x+y)(x-y) & = & x^{2}-xy+xy-y^{2}\nonumber \\
|
||||
& = & x^{2}-y^{2}
|
||||
\end{eqnarray}
|
||||
|
||||
\end_inset
|
||||
|
||||
|
||||
\layout Standard
|
||||
|
||||
Het is mogelijk meerdere regels te voorzien van een etiket.
|
||||
Uit de volgende reeks van vergelijkingen kunnen we verwijzen naar de vergelijki
|
||||
ngen (
|
||||
\begin_inset LatexCommand \ref{eq:gs1}
|
||||
|
||||
\end_inset
|
||||
|
||||
) en (
|
||||
\begin_inset LatexCommand \ref{eq:gs2}
|
||||
|
||||
\end_inset
|
||||
|
||||
) door gebruik te maken van hun overeenkomstige labels.
|
||||
\layout Standard
|
||||
|
||||
|
||||
\begin_inset Formula \begin{eqnarray}
|
||||
v_{k+1} & = & w_{k}+b_{1}\label{eq:gs1} \\
|
||||
w_{k+1} & = & v_{k+1}+b_{2}
|
||||
\end{eqnarray}
|
||||
|
||||
\end_inset
