#include "slepceps.h" PetscErrorCode EPSDenseHessenberg(PetscInt n_,PetscInt k,PetscScalar *A,PetscInt lda_,PetscScalar *Q)Not Collective
n | - dimension of the matrix | |
k | - first active column | |
lda | - leading dimension of A |
A | - on entry, the full matrix; on exit, the upper Hessenberg matrix (H) | |
Q | - on exit, orthogonal matrix of vectors A = Q*H*Q' |
Both A and Q are overwritten.
This routine uses LAPACK routines xGEHRD and xORGHR/xUNGHR.
