numpy.polynomial.hermite_e.hermemul(c1, c2)
[source]
Multiply one Hermite series by another.
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: 


Returns: 

In general, the (polynomial) product of two Cseries 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.
>>> from numpy.polynomial.hermite_e import hermemul >>> hermemul([1, 2, 3], [0, 1, 2]) array([14., 15., 28., 7., 6.])
