In MATLAB, how do I plot to an image and save the result without displaying it?

Question

This question kind of starts where this question ends up. MATLAB has a powerful and flexible image display system which lets you use the imshow and plot commands to display

Answer 1

Here is a completely different answer:

If you want an image file out, why not just save the image instead of the entire figure?

im = magic(10)
imwrite(im/max(im(:)),'magic.jpg')

Then prove that it worked.

imshow('magic.jpg')

This can be done for indexed and RGB also for different output formats.
