# cupy.fft.ihfft¶

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

Compute the FFT of a signal that has Hermitian symmetry.

Parameters
• a (cupy.ndarray) – Array to be transform.

• n (None or int) – Number of points along transformation axis in the input to use. 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") – Keyword to specify the normalization mode.

Returns

The transformed array which shape is specified by n and type will convert to complex if the input is other. The length of the transformed axis is n//2+1.

Return type

cupy.ndarray
