Abstract：Least square generalized inverse was investigated by using the expressions of maximal and minimal ranks of generalized Schur complement .Some formulas for the extremal rank of expressions of submatrices of Least square generalized inverse are derived ,and necessary and sufficient conditions are given for the existence of Least square generalized inverse with special structure .
Keywords：M-P inverseLeast square generalized-inversegeneralized Schur complementmaxi-mal and minimal rank
