Write a 3×3 matrix A which A^2 is diagonal while A is not diagonal ?

Mathematics
1 answer:
LenKa [72]4 years ago
3 0

Consider the matrix

A=\begin{bmatrix}0&1&0\\1&0&0\\0&0&1\end{bmatrix}

Multiplying <em>A</em> by itself has the effect of swapping the first and second rows:

A^2=\begin{bmatrix}1&0&0\\0&1&0\\0&0&1\end{bmatrix}

which is diagonal, while <em>A</em> itself is not.
