You can use pcolor() or just put your values inside a disc of a 2D matrix.

It's done all the time in image processing. We always have irregularly shaped regions of interest, called ROIs or masks, and we process just inside the mask. The matrix is rectangular but the regions inside can be any shape whatsoever.
