I need to create noise on a 2-D grid, say: [x,y]=meshgrid(-100:100,-100:100); where I can set the correlation length. I know that I need to take random noise and then filter it somehow, but I don't know how to do that. I've been reading the matlab help files, but it looks like I'd have to take a course in filter design to figure out what I want to do. Anyond have any suggestions for this? I need to read a book on filtering anyway, but I'm in a bit of a hurry on this particular project. Thanks! Ro |
