BVInsertVecs
Insert a set of vectors into the specified columns.
Synopsis
#include "slepcbv.h"
PetscErrorCode BVInsertVecs(BV V,PetscInt s,PetscInt *m,Vec *W,PetscBool orth)
Collective
Input Parameters
| V | - basis vectors
|
| s | - first column of V to be overwritten
|
| W | - set of vectors to be copied
|
| orth | - flag indicating if the vectors must be orthogonalized
|
Input/Output Parameter
| m | - number of input vectors, on output the number of linearly independent
vectors
|
Notes
Copies the contents of vectors W to V(:,s:s+n). If the orthogonalization
flag is set, then the vectors are copied one by one and then orthogonalized
against the previous ones. If any of them is linearly dependent then it
is discarded and the value of m is decreased.
