numpy.polynomial.hermite.hermmulx#
- polynomial.hermite.hermmulx(c)[source]#
Multiply a Hermite series by x.
Multiply the Hermite series c by x, where x is the independent variable.
- Parameters
- carray_like
1-D array of Hermite series coefficients ordered from low to high.
- Returns
- outndarray
Array representing the result of the multiplication.
Notes
The multiplication uses the recursion relationship for Hermite polynomials in the form
\[xP_i(x) = (P_{i + 1}(x)/2 + i*P_{i - 1}(x))\]Examples
>>> from numpy.polynomial.hermite import hermmulx >>> hermmulx([1, 2, 3]) array([2. , 6.5, 1. , 1.5])
