`numpy.polynomial.laguerre:lagcompanion`

Signature

def lagcompanion ( c )

Return the companion matrix of c.

The usual companion matrix of the Laguerre polynomials is already symmetric when c is a basis Laguerre polynomial, so no scaling is applied.

c : array_like: 1-D array of Laguerre series coefficients ordered from low to high degree.
