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}
\begin{equation}
\label{eq:periodischefunktion}
f(t)=f(t+T),
\end{equation}
\begin{figure}[ht]
\renewcommand*\figurename{Gleichung}
\[

\begin{array}{*{3}{c}}

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} =

\end{array}

\]
\caption{Steifigkeitsmatrix bei Auskragung $A=0$~mm}
\label{eq:steifmatrix0}
\end{figure}
\end{document}
\stepcounter{figure}
just after\begin{figure}
should do the job.\stepcounter{figure} just after
\begin{figure}` yields the desired output.
