I have a MATLAB program I'm running in parallel. I understand that I can't use a worker process to plot to the screen. But, I'm curious, is it possible to use a worker process to plot directly to a file?

You can plot in parfor, it's just you won't see it, but the handle is still there. Then you can use saveas to save it to a file.
parfor i=1:5
saveas(gcf,['temp' num2str(i) '.jpg']);

I tried the code, but got the following error:
% Error using validate (line 162)
% Printing of uicontrols is not supported on this platform.
% Error in print (line 67)
% pj = validate( pj );
% Error in saveas (line 181)
% print( h, name, ['-d' dev{i}] )
% Error in Untitled (line 1)
% parfor i=1:5
Using Matlab 2017b. Any solution for this?
Thanks in Advance
Edit: Found another examle of this with figure() instead of figure(var). Thats the solution.
