Computes the sample points and weights for Gauss-Hermite quadrature. These sample points and weights will correctly integrate polynomials of degree or less over the interval with the weight function .
- deg : int
Number of sample points and weights. It must be >= 1.
- x : ndarray
1-D ndarray containing the sample points.
- y : ndarray
1-D ndarray containing the weights.
New in version 1.7.0.
The results have only been tested up to degree 100, higher degrees may be problematic. The weights are determined by using the fact that
where is a constant independent of and is the k’th root of , and then scaling the results to get the right value when integrating 1.
