See Explanation.

Let us recall that $[M]$ is an $mxxn$ matrix, and $[N]$ is an $nxxp$

matrix, then, we can perform their multiplication in that order and

have $[MN]$ an $mxxp$ matrix.

Accordingly, [A]^2 is undefined.

If we treat $A$ as $vec A$ , then, $vec A^2=vec A*vecA$

$=1^2+3^2+2^2=14$ .

How do you find A^2 given A=((1, 3, 2))A=((1, 3, 2))?
