numpy.polynomial.laguerre.poly2lag()

numpy.polynomial.laguerre.poly2lag(pol) [source]

Convert a polynomial to a Laguerre 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 Laguerre series, ordered from lowest to highest degree.

Parameters:

Parameters:	pol : array_like 1-D array containing the polynomial coefficients
Returns:	c : ndarray 1-D array containing the coefficients of the equivalent Laguerre series.

pol : array_like

1-D array containing the polynomial coefficients

Returns:

c : ndarray

1-D array containing the coefficients of the equivalent Laguerre 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.laguerre import poly2lag
>>> poly2lag(np.arange(4))
array([ 23., -63.,  58., -18.])
