Convert a polynomial to a Hermite series.
Convert an array representing the coefficients of a polynomial (relative to the “standard” basis) ordered from lowest degree to highest, to an array of the coefficients of the equivalent Hermite series, ordered from lowest to highest degree.
- pol : array_like
1-D array containing the polynomial coefficients
- c : ndarray
1-D array containing the coefficients of the equivalent Hermite series.
The easy way to do conversions between polynomial basis sets is to use the convert method of a class instance.
>>> from numpy.polynomial.hermite import poly2herm >>> poly2herm(np.arange(4)) array([1. , 2.75 , 0.5 , 0.375])
