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.
