numpy.polynomial.laguerre.lagcompanion

numpy.polynomial.laguerre.lagcompanion(c)[源代码]

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).
