Hi Stefan- I don't think there is a built-in routine to generate the data you are looking for. If you have an algorithm or approach to do so, we can suggest ways to implement.

Dear All, Do you know how to generate spatially correlated random variables with pdl? Lognormal distribution is preferred, but Gaussian would be acceptable. What CPAN modules could be helpful? I need to generate random material properties for data points in space (x, y, z). The properties don't change abruptly, but rather transition smoothly. In other words, the correlation has a finite radius, d, and then it disappears. Your help will be appreciated. Thank you, Stefan ------------------------------------- Stefan Szyniszewski, Ph.D.,P.E.
