Hello, I have been trying to use the code from the Numerical Recipes in C book. I'm not sure which edition (there are two aren't there?) I copied the code from. However, I am not getting correct values for the convolution. Has anyone had any experience with these routines (convolution and the fft stuff)? Are there any bugs in the code? I've checked mine with the book a number of times and feel 95% confident that my code is consistent with the book. Any help is appreciated. This convolution is a small part in a bigger program for my research and I've been bogged on it for many weeks now. Someone would be much in my debt if they can shed light here. charles d. kincaid p.s. btw, am I alone in believing that the documentation for the code is very poor. They do a good job explaining the theory behind the code (for fft stuff at least), but then they use bad variables and don't explain why the code works. It could be just me. chuck -- charles d. kincaid STATS: (904) 392-1941 statman@stat.ufl.edu CIRCA: (904) 392-2007 'Damn fine coffee...and hot, too!'
