numpy.polynomial.hermite_e.hermecompanion(c)
[source]
Return the scaled companion matrix of c.
The basis polynomials are scaled so that the companion matrix is symmetric when c
is an HermiteE basis polynomial. This provides better eigenvalue estimates than the unscaled case and for basis polynomials the eigenvalues are guaranteed to be real if numpy.linalg.eigvalsh
is used to obtain them.
