- How to prove $(AB)^T=B^T A^T$ - Mathematics Stack Exchange
Given an m × n m × n -matrix A A and an n × p n × p -matrix B B Prove that (AB)T = BTAT (A B) T = B T A T Here is my attempt: Write the matrices A A and B B as A = [aij] A = [a i j] and B = [bij] B = [b i j], meaning that their (i, j) (i, j) -th entries are aij a i j and bij b i j, respectively Let C = AB = [cij] C = A B = [c i j], where cij =∑n k=1aikbkj c i j = ∑ k = 1 n a i k b k

- A confusion in the proof of $(AB)^T = (B^T A^T)$
