Hi:
I met a problem using 'print' function to print contour to 'jpeg' file. I found some suggestions in web: https://www.mathworks.com/matlabcentral/answers/96864-why-does-the-print-command-take-so-long-with-a-scatter-plot-in-matlab-7-5-r2007b, which suggests to print to 'EPS' format would be faster, however, I tested print both 'jpeg' and 'EPS' format, the result looks quite similar.
is there anyway to optimize this process? I attached a sample for test, the data is the 1st graph in a 3*3 contour, it cost about 90 seconds in my side to print the full graph, in both '.jpeg' and '.eps' format.
the test data 'f.mat' is too large, I compress it to .7z and the .zip, therefore, it requires to extract two times.
Thanks!
Yu

Here are the times in my computer. Do you need the '-tiff', '-r600' option for eps file?
tic
print('EPS_test.eps','-depsc2','-opengl');
toc %0.45s
tic
print('EPS_test.eps','-depsc2','-painters');
toc %3.63s
tic
print('EPS_test.eps','-depsc2','-tiff', '-r600');
toc %2.52s
tic
print('EPS_test.jpg','-djpeg', '-r600');
toc %1.12s
