cupy.fft.irfft¶

cupy.fft.irfft(a, n=None, axis=-1, norm=None)[source]

Compute the one-dimensional inverse FFT for real input.

Parameters: a (cupy.ndarray) – Array to be transform. n (None or int) – Length of the transformed axis of the output. For n output points, n//2+1 input points are necessary. If n is not given, it is determined from the length of the input along the axis specified by axis. axis (int) – Axis over which to compute the FFT. norm (None or "ortho") – Keyword to specify the normalization mode. The transformed array which shape is specified by n and type will convert to complex if the input is other. If n is not given, the length of the transformed axis is2*(m-1) where m is the length of the transformed axis of the input. cupy.ndarray
