不能说明A满秩,比如A=[1000]就满足A=A2,自然rankA=rankA2.后面的结论是正确的,把A写成Jordan标准...
其余为零的矩阵),秩为1(至少有一个非零向量),就是r(A)=1,这时r(A²)也只有等于1吧?
注意rank(A)=rank(A^2)等价于Ax=0和A^2x=0同解 既然如此,A^3x=A^2(Ax)=0和A^2x=A(Ax)=0也同解 所以rank(A^3)=rank(A^2)=rank(A)
情形1:如果 r 非零,则 rank{Ae1,...,Aes} = s = rank{A^3e1,...,A^3es} 情形2:如果 r=0. 则 rank{Ae1,...,Aes} =rank{e2,...,es,0}= max{s-1,0} rank{A^2e1,...,A^2es}=rank{e3,...,es,0,0}= max{s-2,0} 因为 rankA = rank A^2, ==> ...
