MATLAB: Can not open fig files saved by “saveas” after live script ran

live-script fig-filesMATLAB

Hi, everyone. I encountered a problem in Matlab2019b these days.

I want to save the .fig files and .eps files after the live script done with

saveas(gcf,'path/fig_name','fig')
print(gcf,'path/fig_name','-r300','-depsc')

Everyting is fine with those .eps files. However, those fig files were also saved but I just can't open them.

If I select the plotting commands, press F9 run them again, replot the figures in private windows as .m script do, then those saved fig files can be opened with matlab.

Any advice will be appreciated.

Thx!

fig = openfig('1t6e7_85Hfluxc17.fig');
fig.Visible = 'on';

That is, that your figures are being created, but their visibility is set to off.

fig = openfig('FigFileName.fig', 'new', 'invisible');
imgs = findobj(fig, '-type', 'image');
thiscmap = get(fig, 'colormap');
for K = 1 : length(imgs)
  thisimg = get(imgs(K), 'CData');
    %now do something with it for illustration purposes
    thisfilename = sprintf('extracted_image_%03d.jpg', K);
    imwrite(thisimg, thiscmap, thisfilename);
  end

Did you type those inside a function or in the command window?

h=figure(5);
figHandles = get(groot, 'Children')

For example,

h=figure(5);
figHandles = get(groot, 'Children');
clear h  % clears the variable in the workspace
close(h) % h is deleted so it will obviously give an error. 
close(figHandles) % figHandles is an instance of figure object. This should close your figure even if you deleted h from the workspace. 
% be sure about which workspace you are working in.

If you create your figure in a function and if the function does not include any close action, after that function executed, you can't close it because your workspaces has changed from "function workspace" to "base workspace". If this is your case, add an output value to your function which is the handle of your figure object. (in here it is "h").

You should read more about handle classes to understand what happens when you create an instance of an object.
