BVBiorthonormalizeColumn
Bi-orthonormalize a column of two BV objects.
Synopsis
#include "slepcbv.h"
PetscErrorCode BVBiorthonormalizeColumn(BV V,BV W,PetscInt j,PetscReal *delta)
Collective
Input Parameters
| V | - first basis vectors context
|
| W | - second basis vectors context
|
| j | - index of column to be bi-orthonormalized
|
Output Parameters
| delta | - (optional) value used for normalization
|
Notes
This function first bi-orthogonalizes vectors V[j],W[j] against W[0..j-1],
and V[0..j-1], respectively. Then, it scales the vectors with 1/delta, so
that the resulting vectors satisfy W[j]'*V[j] = 1.
