numpy.polynomial.polynomial.polycompanion#
- polynomial.polynomial.polycompanion(c)[source]#
Return the companion matrix of c.
The companion matrix for power series cannot be made symmetric by scaling the basis, so this function differs from those for the orthogonal polynomials.
- Parameters:
- carray_like
1-D array of polynomial coefficients ordered from low to high degree.
- Returns:
- matndarray
Companion matrix of dimensions (deg, deg).
