Problem Saving UIFigures when running in parallel

Attempts to save UIFigure inside a parfor loop using getframe or exportgraphics dont seem to work. Returning the error that these functions cant be used in nodisplay mode. I rely on a 3rd party function ft_topoplot_er to plot certain topographs on my UIFigure and save the resulting video, but these calls take some time done sequentially, so I wished to parallelise them using parfor yet I'm unable to do so.

Hi Eli,

You can try using "exportapp" that exports the contents of the figure specified by fig and stores it in the file specified by filename. All graphical content is captured, including UI components.

You can use it in the following manner:

exportapp(fig,filename)

Kindly refer to the following documentation for more information:
