Save Matlab invisible plot under terminal as an image with same size

by

Use the following sequence of commands to connect and start MATLAB:

ssh -x user@server          # disabled X11 forwarding
unset DISPLAY               # unset DISPLAY variable
matlab -nodisplay           # start MATLAB without the desktop

then a simple plot to illustrate:

figure, close                    # must do this first, otherwise plot is empty
plot(1:10)                       # usual plotting
print file                       # save the figure as file.ps
saveas(gcf, 'file.eps', 'eps2c') # saveas aslo works
exit                             # done

I just tried it myself, and it works as expected.

EDIT:

You can always specify the DPI resolution using -r<number>, for example a very high resolution:

print -dpdf -r600 file.pdf

Note that you can use -r0 to specify screen resolution.

Also you can turn on WYSIWYG printing of figures using the PaperPositionMode property:

figure, close
plot(1:10)
set(gcf, 'PaperPositionMode', 'auto')
print -deps2c -r0 file.eps
exit
