function

`scipy.special._orthogonal:_newton`

source: /scipy/special/_orthogonal.py :1184

Signature

def _newton ( n , x_initial , maxit = 5 )

Summary

Newton iteration for polishing the asymptotic approximation to the zeros of the Hermite polynomials.

Parameters

n : int: Quadrature order
x_initial : ndarray: Initial guesses for the roots
maxit : int: Maximal number of Newton iterations. The default 5 is sufficient, usually only one or two steps are needed.

Returns

nodes : ndarray: Quadrature nodes
weights : ndarray: Quadrature weights
