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
- carray_like
1-D array of Laguerre series coefficients ordered from low to high degree.
- Returns
- matndarray
Companion matrix of dimensions (deg, deg).
Notes
New in version 1.7.0.
