function
numpy.polynomial.laguerre:lagmul
Signature
def lagmul ( c1 , c2 ) Summary
Multiply one Laguerre series by another.
Extended Summary
Returns the product of two Laguerre series c1 * c2. The arguments are sequences of coefficients, from lowest order "term" to highest, e.g., [1,2,3] represents the series P_0 + 2*P_1 + 3*P_2.
Parameters
c1, c2: array_like1-D arrays of Laguerre series coefficients ordered from low to high.
Returns
out: ndarrayOf Laguerre series coefficients representing their product.
Notes
In general, the (polynomial) product of two C-series results in terms that are not in the Laguerre polynomial basis set. Thus, to express the product as a Laguerre series, it is necessary to "reproject" the product onto said basis set, which may produce "unintuitive" (but correct) results; see Examples section below.
Examples
