mindspore.numpy.hanning(M)[source]

Returns the Hanning window. The Hanning window is a taper formed by using a weighted cosine.

Parameters: M (int) – Number of points in the output window. If zero or less, an empty array is returned.
Returns: Tensor, the window, with the maximum value normalized to one (the value one appears only if the number of samples is odd).
Raises: TypeError – if M is not an int.

Supported Platforms:: Ascend GPU CPU
