Not Collective
| m | - number of rows |
| n | - number of columns |
| nd | - number of block diagonals |
| bs | - each element of a diagonal is an bs x bs dense matrix |
| bdlen | - array of total block lengths of block diagonals |
| diag | - optional array of block diagonal numbers (length nd). For a matrix element A[i,j], where i=row and j=column, the diagonal number is |
| diagv | - pointer to actual diagonals (in same order as diag array), |
