#include "slepcbv.h" PetscErrorCode BVSetActiveColumns(BV bv,PetscInt l,PetscInt k)Logically Collective on bv
|bv||- the basis vectors context|
|l||- number of leading columns|
|k||- number of active columns|
Also in operations such as BVMult() or BVDot(), the first l columns are normally not included in the computation. See the manpage of each operation.
In orthogonalization operations, the first l columns are treated differently: they participate in the orthogonalization but the computed coefficients are not stored.
