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.
