# numpy.polynomial.hermite.Hermite.mapparms

`Hermite.``mapparms`()

  Return the mapping parameters.

  The returned values define a linear map `off + scl*x` that is applied to the input arguments before the series is evaluated. The map depends on the `domain` and `window`; if the current `domain` is equal to the `window` the resulting map is the identity. If the coefficients of the `Hermite` instance are to be used by themselves outside this class, then the linear function must be substituted for the `x` in the standard representation of the base polynomials.

  Returns : | off, scl : floats or complex The mapping function is defined by `off + scl*x`.

  Notes

  If the current domain is the interval `[l_1, r_1]` and the window is `[l_2, r_2]`, then the linear mapping function `L` is defined by the equations:

      L(l_1) = l_2
      L(r_1) = r_2
