      poly2herm(pol)
  
      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.
  
      Parameters
      ----------
      pol : array_like
          1-D array containing the polynomial coefficients
  
      Returns
      -------
      c : ndarray
          1-D array containing the coefficients of the equivalent Hermite
          series.

      Notes
      -----
      The easy way to do conversions between polynomial basis sets
      is to use the convert method of a class instance.
  
      Examples
      --------
      >>> from numpy.polynomial.hermite import poly2herm
      >>> poly2herm(np.arange(4))
      array([ 1.   ,  2.75 ,  0.5  ,  0.375])
