How do I create a JPEG file and/or a plot without opening a figure window?
I want to directly send a plot to a file. In other words, I want to create a JPEG file using the PRINT command, but I do not want a figure window to open.

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:
It is possible to create a JPEG without creating a visible figure window. However, you must create a figure to contain the graphics objects. Here is an example of the code to do so:
h = figure('visible', 'off')
surf(peaks)
print -djpeg test
close(h)
PLEASE NOTE: This method is currently not available for all image formats. In particular, it does not work for bitmaps, and may not work for other formats as well.
