#include "slepcbv.h" PetscErrorCode BVGetColumn(BV bv,PetscInt j,Vec *v)Logically Collective on BV
bv | - the basis vectors context | |
j | - the index of the requested column |
The returned Vec must not be destroyed. BVRestoreColumn() must be called when it is no longer needed. At most, two columns can be fetched, that is, this function can only be called twice before the corresponding BVRestoreColumn() is invoked.
A negative index j selects the i-th constraint, where i=-j. Constraints should not be modified.
