  Given a matrix A = [0   4   3] ,find a matrix B such that B  = A
                     [0   0   1]


  謝謝

→ yimao:eigenvalue=3..2..1..用Sylvester 公式法
→ yimao:打錯...是...9..4..1...
推 scisyhp:把A對角化 B有兩解
→ fs3:對角化然後呢?
→ funtsung:B=A^(1/2)  A=S*D^(1/2)*S^(-1)?
→ john7643:這題雖然沒重根..但感覺..對角化比CayleyHamilition好用
