证明:由于${A^2} = A$,且$r\left( A \right) = r$,则存在可逆阵$P$,使得

Pbubuko.com,布布扣?1bubuko.com,布布扣AP=(Ebubuko.com,布布扣rbubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣0bubuko.com,布布扣bubuko.com,布布扣)bubuko.com,布布扣

即${P^{ - 1}}AP = \left( {

Ebubuko.com,布布扣rbubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣0bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣
} \right)$,令$B = P\left( {
0bubuko.com,布布扣rbubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣Jbubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣0bubuko.com,布布扣bubuko.com,布布扣bubuko.com,布布扣
} \right){P^{ - 1}}$,则命题得证

其中$J$为$s$阶若当块,对角线全为$0$

$\bf注:$若$A$的零化多项式无重根,则$A$可相似对角化
