cupyx.scipy.fft.rfft¶

cupyx.scipy.fft.rfft(x, n=None, axis=-1, norm=None, overwrite_x=False)¶

Compute the one-dimensional FFT for real input.

The returned array contains the positive frequency components of the corresponding fft(), up to and including the Nyquist frequency.

Parameters:	x (cupy.ndarray) – Array to be transformed. n (None or int) – Length of the transformed axis of the output. If `n` is not given, the length of the input along the axis specified by `axis` is used. axis (int) – Axis over which to compute the FFT. norm (None or `'ortho'`) – Normalization mode. overwrite_x (bool) – If True, the contents of `x` can be destroyed.
Returns:	The transformed array.
Return type:	cupy.ndarray
