ifft

caput.algorithms.fft.fftw.ifft(x, axes=None)

Perform an inverse discrete Fourier Transform.

If the fourier transform is to be applied repeatedly to arrays with the same size and dtype, it is faster to use the FFTW class directly to avoid creating new FFTW objects.

Parameters:

xcomplex array_like

Complex input array

axesint | iterable[int], optional

Axes over which to take the ifft. Default is all axes.

Returns:

ifftcomplex ndarray

IDFT of the input array over specified axes
