I have a Matlab .fig file. (Basically a pcolor plot). I want to extract the matrix (like rows and columns into an array variable) from this image. How do I do this? Thanks for any inputs or pointers.

Use getimage() or getframe() depending on what you want to do. Or you can use export_fig to export the whole axes or figure to an image file, like a .PNG file.
