$$A = (a _{ij}) = \left[\begin{matrix}0 & 0 & ... & 0 & 1 \0 & 0 & ... & 2 & 0 \ ... & ... & ... & ... & ... \0 & n-1 & 0 & ... & 0 \n & 0 & 0 & ... & 0 \\end{matrix}\right]$$$$B = (b _{ij}) = \left[\begin{matrix}0 & 1 & 0 & ... & 0 \0 & 0 & 2 & ... & 0 \... & ... & ... & ... & ... \0 & 0 & 0 & ... & n-1 \n & 0 & 0 & ... & 0 \\end{matrix}\right]$$
