- I'm looking for an implementation in C of the Winograd Fourier transform
- algorithm. The usual decimation-in-time algorithms are not suitable for
- my application as I need to perform FFTs on data sets that are not powers
- of two and I do not wish to pad them. I understand other algorithms are
- available to do this, but the Winograd algorithm is supposedly the best
- one [1]. Thanks.
