numpy.polynomial.hermite.hermmul(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 seriesP_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.
Examples
>>> from numpy.polynomial.hermite import hermmul >>> hermmul([1, 2, 3], [0, 1, 2]) array([ 52., 29., 52., 7., 6.])
numpy.polynomial.hermite.hermmul()
