int PCNullSpaceCreate(MPI_Comm comm, int has_cnst, int n, Vec *vecs,PCNullSpace *SP)Collective on MPI_Comm
comm | - the MPI communicator associated with the object |
has_cnst | - PETSC_TRUE if the null space contains the constant vector; otherwise PETSC_FALSE |
n | - number of vectors (excluding constant vector) in null space |
vecs | - the vectors that span the null space (excluding the constant vector); these vectors must be orthonormal |
