Creating a 512 x 512 image from 600 x 800

The idea is to have 512 pixels in both rows and columns of my image. I'm not sure which function I would use to do so. Any ideas?

Try imresize(). This syntax:

B = imresize(A, [numrows numcols])

should allow you to scale an image without preserving the original aspect ratio.

Thank you! Now I have added a colored image to my workspace, but using colormap(gray) it is still colored. Any ideas?
