# numpy.polynomial.hermite.hermmulx

`numpy.polynomial.hermite.``hermmulx`(c)

  Multiply a Hermite series by x.

  Multiply the Hermite series c by x, where x is the independent variable.

  Parameters : | c : array_like 1-D array of Hermite series coefficients ordered from low to high.
  Returns : | out : ndarray 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])
