Hello,

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?

Thanks,

Mark

在 MATLAB Online 中打开

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
        figure(i)
        plot(rand(i*10,1));
        saveas(gcf,['temp' num2str(i) '.jpg']);
    end

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
