| B | - the matrix | |
| bs | - size of block, the blocks are ALWAYS square. | |
| i | - the indices into j for the start of each local row (starts with zero) | |
| j | - the column indices for each local row (starts with zero) these must be sorted for each row | |
| v | - optional values in the matrix |
