# numpy.polynomial.hermite.Hermite

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

  A Hermite series class.

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

  Parameters:
    coef array_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.].

    symbol str, 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
