Question

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

Answer 1

See Explanation.

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`.
