FFT for arbitrary time and frequency grids (Chirp-z Transform) [Matlab]
The FFT is usable only for specific values of the time and frequency spacings; (their product must be the inverse of a highly composite integer). In practice, however, we find arbitrary sp... posted by Jesus Selva on Nov 17 2011
