optimization optimplot capture frame

Hi,

I would like to create movie out of "optimplot" of fmincon function. For that I need to get hadle to this optimplot figure in order to capture frame.

% Capture frame for movie
frame = getframe(fighndl);

How to get this handle? Is there another solution to create movie out of optimplot?

optimplot does not plot in a figure container of the type that you can get a handle to.

Prior to R2025, you could probably have worked around this by writing a second PlotFcn that performs a screen capture, with any of the Java-based screen capture tools on the File Exchange,

Since R2025 does not use Java, you will instead probably have to render the plots with your own PlotFcn instead of optimplot.
