chainer.functions.fft(x)[source]

Fast Fourier transform.

Parameters: x (tuple) – (real, imag) where real is a Variable storing the real part and imag is a Variable storing the imaginary part. Returns (ry, ri) where ry is the real part of the result and ri is the imaginary part of the result. tuple

Note

Currently this function supports a tuple as input. It will support a complex numbers directly in the future.
