#include "slepcbv.h" 
PetscErrorCode BVGetMat(BV bv,Mat *A)

Collective

Input Parameter#

  • bv - the basis vectors context

Output Parameter#

  • A - the matrix

Notes#

The returned matrix contains only the active columns. If the content of the Mat is modified, these changes are also done in the BV object. The user must call BVRestoreMat() when no longer needed.

This operation implies a call to BVGetArray(), which may result in data copies.
