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])

An Hermite series class.

Arithmetic

hermadd(c1, c2)

Add one Hermite series to another.

hermsub(c1, c2)

Subtract one Hermite series from another.

hermmulx(c)

Multiply a Hermite series by x.

hermmul(c1, c2)

Multiply one Hermite series by another.

hermdiv(c1, c2)

Divide one Hermite series by another.

hermpow(c, pow[, maxpower])
