BVSetNumConstraints

Set the number of constraints.

Synopsis

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

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.
