(deg)[源代码]¶ GaussHermite quadrature.
Computes the sample points and weights for GaussHermite quadrature. These sample points and weights will correctly integrate polynomials of degree or less over the interval with the weight function .
Parameters:  deg : int
Number of sample points and weights. It must be >= 1.
Returns:  x : ndarray
1D ndarray containing the sample points.
 y : ndarray
1D ndarray containing the weights.
Notes
1.7.0 新版功能.
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.
