#include "slepceps.h" PetscErrorCode EPSQRDecomposition(EPS eps,Vec *V,int m,int n,PetscScalar *R,int ldr)Collective on EPS
| eps | - the eigenproblem solver context | |
| V | - set of vectors | |
| m | - starting column | |
| n | - ending column | |
| ldr | - leading dimension of R |
In some cases, this routine makes V B-orthonormal, that is, V'*B*V=I.
If one of the vectors is linearly dependent wrt the rest (at working precision) then it is replaced by a random vector.
