Parameters:

  • a (ArrayLike) – Array to apply the weighting function onto.

  • domain_l (float) – Domain lowest possible value, values less than domain_l will be set to zero.

  • domain_h (float) – Domain highest possible value, values greater than domain_h will be set to zero.

Returns:

Weighted array.

Return type:

numpy.ndarray
