xoa.filter.get_window_func(window, **kwargs)

Get a window function from its name

Parameters:

• window (str, callable, list, array_like) –

  Specification to get the window function:

  • callable: used as is.

  • str: supposed to be function name of the numpy or scipy.signal.windows modules.

  • list, array_like: transformed to an array and interpolated onto size points.

• kwargs – Argument passed to the low level window function at calling time.

Returns:

callable – A function that takes only a size argument

Example

In [1]: func0 = get_window_func("gaussian", std=22, sym=True)

In [2]: func1 = get_window_func([1, 2, 5, 2, 1])

In [3]: plt.plot(func0(100), label='Gaussian');

In [4]: plt.plot(func1(100), label='List/array');

In [5]: plt.legend();
