From: Randy Cole <COLE@USC-ISIB> In the current issue of Personal Computer Age there is an excellent article comparing the new Microsoft Fortran (v. 3.10) and the latest Supersoft Fortran. The issue is Volume 2.9 (they don't believe in months). It does a good job of pointing out the real advantages and disadvantages of each and doesn't get too hung up about benchmarks. Although Fast Fourier Transforms transform a complex vector in some domain into a complex vector in the frequency domain, Fortran FFTs need not use the COMPLEX type, and there are lots of FFTs around that don't. One example is the package called FAST, from the book IEEE Programs for Digital Signal Processing, which is also available on mag tape. It is a radix 2-4-8 FFT with special provisions for real input vectors, etc. Randy Cole Cole@ISIB -------
