def _initial_nodes ( n )

Summary

Initial guesses for the Hermite roots

Extended Summary

Computes an initial approximation to the non-negative roots $x_{k}$ of the Hermite polynomial $H_{n}$ of order $n$ . The Tricomi and Gatteschi initial guesses are used in the region where they are accurate.

Parameters

n : int: Quadrature order

Returns

xk : ndarray: Approximate roots
