CTF is the best I know for what it does. But I think it might be a bit like MatFFTW in that a supported Mat impl would be a maintenance burden of marginal value. (I would argue that the most common use of FFT in scientific computing is in the form of a convolution, for which the abstraction leaks and needs to be composed anyway.) I could be wrong, and if someone is using CTF and sees a good way to make a useful MatCTF and has the energy to do so, I think it would be welcome.
