sine and cosine transforms?
I'm thinking about adding sine and cosine transforms when I find some time.
The main reason is that
scipy.fft offers these transforms but will fall back to
scipy.fftpack if they are called. I'm not worried about performance but rather about accuracy, which is notoriously bad for
fftpack's real transforms (if the transform sizes are near-prime).
Also, at the moment, existing programs using
scipy that do not switch explicitly to
scipy.fft won't benefit from the new library and still use
fftpack, correct? If
fftpack's full functionality, then maybe it could replace
fftpack entirely (behind
scipy.fftpack's original interface, of course).
@peterbell10, do you think this is a useful plan? Or will it be too tedious to put
pypocketfft behind the
