numpy.polynomial.laguerre.lagcompanion

numpy.polynomial.laguerre.lagcompanion(c) [source]

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.

Parameters:

c : array_like

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

Returns:

mat : ndarray

Companion matrix of dimensions (deg, deg).

Notes

New in version 1.7.0.
