I know you are going to tell me to search in the faq. But my problem is not there.
The thing is this: I diveded the space between -2 and 2, both in x and in y axes, in little cells of 0.04x0.04. I have to generate random numbers in each cell, in that range, but I have not found the way to manipulate drand48() function to do that.
Thanks a lot!"!
