Hi, I have a sparse cloud of points of ~10^4 points randomly scattered around a triangular domain [1] from which I want to take the Fourier transform. I have been looking for algorithms and found one library, but only appears to be for the 1-D case (and seems there is no documentation). In [3] there is C code for the FFTW, but seems it code is itself pruned (pun intended).
Does anyone have a clue about how to perform it? Speed is not a big issue, but accuracy is quite important. Thanks, David. [1] http://www.asaaf.org/~davidmh/coverage.png [2] https://pypi.python.org/pypi/pynfftls/1.0 [3] http://www.fftw.org/pruned.html
