BVBiorthogonalizeColumn#

Bi-orthogonalize a column of two BV objects.

Synopsis#

#include "slepcbv.h"   
PetscErrorCode BVBiorthogonalizeColumn(BV V,BV W,PetscInt j)

Collective

Input Parameters#

  • V - first basis vectors context

  • W - second basis vectors context

  • j - index of column to be bi-orthonormalized

Notes#

This function bi-orthogonalizes vectors \(v_j\), \(w_j\) against \(W_{0:j-1}\), and \(V_{0:j-1}\), respectively, so that \(W_{0:j}^*V_{0:j}\) is diagonal.
