PetscErrorCode BVSetSizes(BV bv,PetscInt n,PetscInt N,PetscInt m)
Collective
Input Parameters#
bv - the basis vectors
n - the local size (or
PETSC_DECIDEto have it set)N - the global size (or
PETSC_DECIDE)m - the number of columns
Notes#
n and N cannot be both PETSC_DECIDE.
If one process calls this with N equal to PETSC_DECIDE then all processes must,
otherwise the program will hang.
