Temperton's FFT routines perform multiple Fast Fourier Transforms. It performs a number of simultaneous complex periodic fourier transforms or corresponding inverse transforms. That is, given a set of real gridpoint vectors, the package returns a set of complex fourier coefficient vectors, or vice versa. the length of the transforms must be a number greater than 1 that has no prime factors other than 2, 3, and 5
