numpy.polynomial.hermite.Hermite

class numpy.polynomial.hermite.Hermite(coef, domain=None, window=None, symbol='x')

An Hermite series class.

The Hermite class provides the standard Python numerical methods ‘+’, ‘-’, ‘*’, ‘//’, ‘%’, ‘divmod’, ‘**’, and ‘()’ as well as the attributes and methods listed below.

Parameters:

coefarray_like

Hermite coefficients in order of increasing degree, i.e, (1, 2, 3) gives 1*H_0(x) + 2*H_1(x) + 3*H_2(x).

domain(2,) array_like, optional

Domain to use. The interval [domain[0], domain[1]] is mapped to the interval [window[0], window[1]] by shifting and scaling. The default value is [-1, 1].

window(2,) array_like, optional

Window, see domain for its use. The default value is [-1, 1].

New in version 1.6.0.

symbolstr, optional

Symbol used to represent the independent variable in string representations of the polynomial expression, e.g. for printing. The symbol must be a valid Python identifier. Default value is ‘x’.

New in version 1.24.

Attributes:

symbol
