numpy.polynomial.hermite_e.hermemulx(c)
[source]
Multiply a Hermite series by x.
Multiply the Hermite series c
by x, where x is the independent variable.
Parameters: |
c : array_like 1-D array of Hermite series coefficients ordered from low to high. |
---|---|
Returns: |
out : ndarray Array representing the result of the multiplication. |
The multiplication uses the recursion relationship for Hermite polynomials in the form
xP_i(x) = (P_{i + 1}(x) + iP_{i - 1}(x)))
