# numpy.polynomial.laguerre.lagcompanion

`numpy.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).
