function

numpy.polynomial.hermite_e:hermemul

source: /numpy/polynomial/hermite_e.py :445

Signature

def   hermemul ( c1 ,  c2 )

Summary

Multiply one Hermite series by another.

Extended Summary

Returns the product of two Hermite series c1 * c2. The arguments are sequences of coefficients, from lowest order "term" to highest, e.g., [1,2,3] represents the series P_0 + 2*P_1 + 3*P_2.

Parameters

c1, c2 : array_like

1-D arrays of Hermite series coefficients ordered from low to high.

Returns

out : ndarray

Of Hermite series coefficients representing their product.

Notes

In general, the (polynomial) product of two C-series results in terms that are not in the Hermite polynomial basis set. Thus, to express the product as a Hermite series, it is necessary to "reproject" the product onto said basis set, which may produce "unintuitive" (but correct) results; see Examples section below.
