tensor.hann_window

   fn hann_window(size: T, periodic: Option<usize>) -> Tensor<T>;

Generates a Hann window as described in the paper https://ieeexplore.ieee.org/document/1455106.

• size(T) - A scalar value indicating the length of the window.

• periodic(Option) - If 1, returns a window to be used as periodic function. If 0, return a symmetric window. When 'periodic' is specified, hann computes a window of length size + 1 and returns the first size points. The default value is 1.

Returns

A Hann window with length: size. The output has the shape: [size].
