[ANN] FFTInterpolations.jl - sinc interpolation based on FFTs

Hey,

after looking for a sinc interpolation method based on FFTs, I recently created a small package for it on GitHub which works for both up and downsampling on multi dimensional arrays.

There was also a long discussion about different boundary handlings in this thread.

Since FFT based interpolations are not as flexible as the algorithms of Interpolations.jl, I didn’t include the algorithms there.

I would be happy about feedback what could be fixed, improved and added since I’m not really familiar with digital signal processing :smile:

Thanks,

Felix

Since Interpolations does not really mean downsampling, I changed the name:
FFTResampling.jl
