If so what would be the properties of the Matrix A and B?

I know this seems like a homework question but I genuinely want to know

[math]AB=A^T[/math]
[math]B = A^{-1} A^T[/math]
Ask this stuff in sqt, for Christ's sake.

If there were such a T, we would have [math]T = T X I = I^T = I[/math], where [math]I[/math] is the identity.
But that would mean that [math]A = I X A = T X A = A^T[/math] for all matrices A i.e all matrices are their tranpose.

So no, you can't.

Linear algebra proofs like this are really easy if you just write down the question in terms of matrix multiplication and use the properties given by your textbook, idk why you'd make a thread.

He didn't require the B to be the same for all matrices

>>11464212
is transpose a linear operation?
does it satisfy T(aA + bB) = aT(A) + bT(B)?
if so, then since matricies are finite dimensional vector spaces, then yes, you can construct a matrix to do that.
