# numpy.polynomial.laguerre.lagcompanion

polynomial.laguerre.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.

  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.
