| Abstract: |
| In the sense of complex number, some rank equalities through the special factorizations of the block matrix are studied in this paper, and some Moore-Penrose inverse of the block matrix are come through some rank qualities and other rank equalities from biliography[2]. |
| Key words: special factorization block matrix rank equality |
