Hessenberg (const Matrix< C > &A) | |
default constructor, perform the Hessenberg transformation |
Convert a given matrix A into Hessenberg form B=U^T*A*U, where U is orthogonal. We do not store the U-matrix, since this routine is the main ingredient in the numerical solution of the nonsymmetric eigenvalue problem.
