EPSDenseHEP

Solves a dense standard Hermitian Eigenvalue Problem.

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSDenseHEP(PetscInt n_,PetscScalar *A,PetscInt lda_,PetscReal *w,PetscScalar *V)
Not Collective

Input Parameters

n - dimension of the eigenproblem
A - pointer to the array containing the matrix values
lda - leading dimension of A

Output Parameters

w - pointer to the array to store the computed eigenvalues
V - pointer to the array to store the eigenvectors

Notes

If V is PETSC_NULL then the eigenvectors are not computed.

Matrix A is overwritten.

This routine uses LAPACK routines DSYEVR or ZHEEVR.
