# HermiteE Module, “Probabilists’” (numpy.polynomial.hermite_e)¶

New in version 1.6.0.

This module provides a number of objects (mostly functions) useful for dealing with HermiteE series, including a HermiteE 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).

## HermiteE Class¶

 HermiteE(coef[, domain, window]) An HermiteE series class.

## Basics¶

 hermeval(x, c[, tensor]) Evaluate an HermiteE series at points x. hermeval2d(x, y, c) Evaluate a 2-D HermiteE series at points (x, y). hermeval3d(x, y, z, c) Evaluate a 3-D Hermite_e series at points (x, y, z). hermegrid2d(x, y, c) Evaluate a 2-D HermiteE series on the Cartesian product of x and y. hermegrid3d(x, y, z, c) Evaluate a 3-D HermiteE series on the Cartesian product of x, y, and z. hermeroots(c) Compute the roots of a HermiteE series. hermefromroots(roots) Generate a HermiteE series with given roots.

## Fitting¶

 hermefit(x, y, deg[, rcond, full, w]) Least squares fit of Hermite series to data. hermevander(x, deg) Pseudo-Vandermonde matrix of given degree. hermevander2d(x, y, deg) Pseudo-Vandermonde matrix of given degrees. hermevander3d(x, y, z, deg) Pseudo-Vandermonde matrix of given degrees.

## Calculus¶

 hermeder(c[, m, scl, axis]) Differentiate a Hermite_e series. hermeint(c[, m, k, lbnd, scl, axis]) Integrate a Hermite_e series.

## Algebra¶

 hermeadd(c1, c2) Add one Hermite series to another. hermesub(c1, c2) Subtract one Hermite series from another. hermemul(c1, c2) Multiply one Hermite series by another. hermemulx(c) Multiply a Hermite series by x. hermediv(c1, c2) Divide one Hermite series by another. hermepow(c, pow[, maxpower]) Raise a Hermite series to a power.

 hermegauss(deg) Gauss-HermiteE quadrature. hermeweight(x) Weight function of the Hermite_e polynomials.

## Miscellaneous¶

 hermecompanion(c) Return the scaled companion matrix of c. hermedomain hermezero hermeone hermex hermetrim(c[, tol]) Remove “small” “trailing” coefficients from a polynomial. hermeline(off, scl) Hermite series whose graph is a straight line. herme2poly(c) Convert a Hermite series to a polynomial. poly2herme(pol) Convert a polynomial to a Hermite series.
