# equation number to caption

I am trying to change the number in the caption of the figure. It should be the following number of the equation. So instead of "Gleichung 0.1" i want "Gleichung 0.2" in the caption (see picture). I don't mind typing those numbers manually, since it's only for 4 following figures that have to follow on the equation number. Plus i don't have any other equations afterwards, in that chapter (if it helps). But i have a lot of figures following, which numbers should not be changed! I have tried a couple of instructions i've found like: \usepackage{chngcntr} or something similar, but i couldn't figure it out yet. That's why i come to you with this MWE.

If i could keep the figure command and type in the numbering manually without changing the numbers of the following figures, you would help me already;)

EDIT: The actual document and numbering is shown in the last picture.

MWE:

\documentclass{scrreprt}
\usepackage{amsmath, amssymb}

\begin{document}

$$\label{eq:periodischefunktion} f(t)=f(t+T),$$

\begin{figure}[ht]
\renewcommand*\figurename{Gleichung}
$\left| \begin{array}{*{3}{c}} c_{F_x\vec{x}} & c_{F_y\vec{x}} & c_{F_z\vec{x}}\\ c_{F_x\vec{y}} & c_{F_y\vec{y}} & c_{F_z\vec{y}}\\ c_{F_x\vec{z}} & c_{F_y\vec{z}} & c_{F_z\vec{z}}\\ \end{array}\right|_{stat} = \left| \begin{array}{*{3}{c}} 410,6 & - & -\\ - & 318,7 & -\\ - & - & -\\ \end{array} \right| \frac{\mbox{N}}{\mbox{mm}}$
\caption{Steifigkeitsmatrix bei Auskragung $A=0$~mm}
\label{eq:steifmatrix0}
\end{figure}

\end{document}


• \stepcounter{figure} just after \begin{figure} should do the job. – barbara beeton Dec 8 '14 at 17:41
• @barbarabeeton i think it's a little bit more complicated. at least i don't know how to get the number to 4.3 (see picture after edit). \stepcounter{figure} brings just 4.16. And what's even worse is that the following captions are affected by this command. – goodstuff Dec 8 '14 at 18:12
• @goodstuff: As suggested by @barbarabeeton, adding \stepcounter{figure} just after \begin{figure} yields the desired output. – Werner Dec 8 '14 at 18:17
• Don't do this. PLease, don't do this. Work in a consitent way. You will regret it at some point. – Johannes_B Dec 8 '14 at 18:21
• As i said, this does only work for the MWE... is there a way to count down that number for the figure 4.15->4.3 WITHOUT affecting figures later in that document! – goodstuff Dec 8 '14 at 18:22

This can go wrong if the figure floats after LaTeX has typeset other numbered equations, but here it is anyway:

\documentclass{scrreprt}
\usepackage{amsmath, amssymb,siunitx}

\begin{document}

$$\label{eq:periodischefunktion} f(t)=f(t+T),$$

\begin{figure}[ht]
\renewcommand*\figurename{Gleichung}
\makeatletter
\let\c@figure\c@equation
\makeatother
$\begin{vmatrix} c_{F_x\vec{x}} & c_{F_y\vec{x}} & c_{F_z\vec{x}}\\ c_{F_x\vec{y}} & c_{F_y\vec{y}} & c_{F_z\vec{y}}\\ c_{F_x\vec{z}} & c_{F_y\vec{z}} & c_{F_z\vec{z}}\\ \end{vmatrix}_{\mathrm{stat}} = \begin{vmatrix} 410,6 & - & -\\ - & 318,7 & -\\ - & - & -\\ \end{vmatrix} \si[per-mode=fraction]{\newton\per\milli\meter}$
\caption{Steifigkeitsmatrix bei Auskragung $A=\SI{0}{\milli\meter}$}
\label{eq:steifmatrix0}
\end{figure}

\begin{figure}[ht]
Normal
\caption{Normal figure}
\end{figure}

Some reference to \ref{eq:steifmatrix0}.

\end{document}


The trick is to make (locally) the caption in the figure environment use equation`.

• awesome, just what i needed. and since there are no further equations afterwards and my numbering is influenced by chapters, it works perfectly. thank you – goodstuff Dec 8 '14 at 18:35
