#include "slepceps.h" PetscErrorCode EPSSortDenseSchur(EPS eps,PetscInt n_,PetscInt k,PetscScalar *T,PetscInt ldt_,PetscScalar *Q,PetscScalar *wr,PetscScalar *wi)Not Collective
eps | - the eigensolver context | |
n | - dimension of the matrix | |
k | - first active column | |
ldt | - leading dimension of T |
T | - the upper (quasi-)triangular matrix | |
Q | - the orthogonal matrix of Schur vectors | |
wr | - pointer to the array to store the computed eigenvalues | |
wi | - imaginary part of the eigenvalues (only when using real numbers) |
Both T and Q are overwritten.
This routine uses LAPACK routines xTREXC.
