Compute eingenvalues of a upper Hessenberg matrix using lapack routine DHSEQR
function eigenValues_dhseqr extends Modelica.Icons.Function; import Modelica_LinearSystems2.Math.Matrices.Internal.eigenvaluesHessenberg; input Real H[:, size(H, 1)] "Real upper Hessenberg matrix"; output Complex zeros[size(H, 1)] "Finite, invariant zeros of ss; size(Zeros,1) <= size(ss.A,1)"; end eigenValues_dhseqr;
