As I have an application that requires thousand's of Fourier Transforms, I am curious as to whether you can use the FEEDBACK function to help crunch the FT's? Does anyone know if this is possible? Several of us have been trying to figure out what Fourier Transforms are used for in graphics processing? Any ideas? Thanks, Tom
