I have a matrix with a limited set of integer values (say 3-4) and I want a display of this matrix in black-and-white. Of course, I can use e.g. the pcolor-function with a few elements grayscale, but I think the result could be more convincing if I could assign a different hatching to the different matrix values, so that areas, where the matrix elements have a particular value, appear with a chosen hatching pattern.
If anyone knows about a way to do this, I would be happy if you could drop me a note. Thank you very much in advance Rolf
