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 | - if the null spaces contains the constant vector, PETSC_TRUE or 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 |
