BVSetNumConstraints#

Set the number of constraints.

Synopsis#

#include "slepcbv.h" 
PetscErrorCode BVSetNumConstraints(BV V,PetscInt nc)

Logically Collective

Input Parameters#

  • V - basis vectors

  • nc - number of constraints

Notes#

This function sets the number of constraints to nc and marks all remaining columns as regular. Normal user would call BVInsertConstraints() instead.

If nc is smaller than the previously set value, then some of the constraints are discarded. In particular, using nc=0 removes all constraints preserving the content of regular columns.
