Hermite Series, “Physicists” (numpy.polynomial.hermite)

This module provides a number of objects (mostly functions) useful for dealing with Hermite series, including a Hermite class that encapsulates the usual arithmetic operations. (General information on how this module represents and works with such polynomials is in the docstring for its “parent” sub-package, numpy.polynomial).

Classes

Hermite(coef[, domain, window, symbol])

An Hermite series class.

Constants

hermdomain	An array object represents a multidimensional, homogeneous array of fixed-size items.
hermzero	An array object represents a multidimensional, homogeneous array of fixed-size items.
hermone	An array object represents a multidimensional, homogeneous array of fixed-size items.
hermx	An array object represents a multidimensional, homogeneous array of fixed-size items.
