× 因为rank(A)=r,故即存在有限个m级初等矩阵的乘积,记为P,和有限个n级初等矩阵的乘积,记为Q.使得:即:令则B为m×r矩阵,且rank(B)=r,C为r×n矩阵,且rank(C)=r,故存在m×r的列满秩矩阵B和r×n的列满秩矩阵C,使得A=BC.反馈 收藏

A^2=A=AB, rank(B)= rank(BA)≤ rankA (Sylvester's rank inequality), rank(A)=rank(AB)≤ rank(B) 这说明 rank(A)=rank(B) 反方向, 如果rank(A)=rank(B), 因为A^2=A=AB,(B)A=BA^2=(BA)A,所以 B=BA,B^2=(BA)^2=BA(BA)=BAB=B(AB)=BA=B,所以 B^2=B=BA ...
