chainer.functions.fft¶

chainer.functions.fft(x)[source]¶

Fast Fourier transform.

Parameters:	x (tuple) – `(real, imag)` where `real` is a `Variable` or an N-dimensional array storing the real part and `imag` is a `Variable` or an N-dimensional array storing the imaginary part.
Returns:	Returns `(ry, iy)` where `ry` is the real part of the result and `iy` is the imaginary part of the result.
Return type:	tuple

Note

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