Are you looking for something like PDF's function shading?
Look for the PDF reference manual, chapter 4.6.3 under 'Type1 (Function-Based)
Shadings'
I've seen cases where this gradient is used with a sample function (chapter
3.9.1) as input. This seems to match what you're trying to accomplish:
set up a 2x2 domain of colors and interpolate between them.

You could approximate the same behavior with a grid of coons patches (= the
matrix) but it would be very verbose.
