slice | - the Sliced object | |
d_nz | - number of block nonzeros per block row in diagonal portion of local submatrix (same for all local rows) | |
d_nnz | - array containing the number of block nonzeros in the various block rows of the in diagonal portion of the local (possibly different for each block row) or PETSC_NULL. You must leave room for the diagonal entry even if it is zero. | |
o_nz | - number of block nonzeros per block row in the off-diagonal portion of local submatrix (same for all local rows). | |
o_nnz | - array containing the number of nonzeros in the various block rows of the off-diagonal portion of the local submatrix (possibly different for each block row) or PETSC_NULL. |
