Hi there,
I am trying to open a figure that I have previously stored in the MATLAB Workspace. The figure has been stored in this way:
f1 = figure; figure(f1); plot(gr_RULE(10:end,1)); title('Rule for k');
However, when I try to open it the following error comes up:
>> openfig(f1)
Error using openFigure
The value of 'Filename' is invalid. It must satisfy the function: ischar.
Error in openfig>localGetFileAndOptions (line 104)
Error in openfig (line 37)
[filename, reuse, visibleAction] = localGetFileAndOptions(varargin);
I would appreciate if sb could let me know how to open them directly from the workspace and not from the directory file.

the answer is: figure(Name_figure). Example: figure(figure(1))

This is because when you close the figure, the object handle is deleted. Read documentation link for more details. You can check this by executing isgraphics(f1) in the command window, which determines the validity of a graphic object handle.
Also refer to the answer here.
Hope this helps!
