function
numpy.polynomial.laguerre:lagcompanion
Signature
def lagcompanion ( c ) Summary
Return the companion matrix of c.
Extended Summary
The usual companion matrix of the Laguerre polynomials is already symmetric when c is a basis Laguerre polynomial, so no scaling is applied.
Parameters
c: array_like1-D array of Laguerre series coefficients ordered from low to high degree.
Returns
mat: ndarrayCompanion matrix of dimensions (deg, deg).
