Since A = A , the dimensions of AT must be the same as the dimensions of A. Therefore, m n must be the same as n m, and so we can conclude that m = n. This means that A is n n, which means that A is a square matrix.

WebThe dot product of two vectors v and w is equivalent to v T w.This can be seen as projecting w onto a line defined by v, and v T by itself can be interpreted as a transformation from î and ĵ onto that line. It turns out transpose is linked to dot product in other ways too. First, let's look at an alternative interpretation of a linear transformation (multiplying by a matrix) as … WebAB is just a matrix so we can use the rule we developed for the transpose of the product to two matrices to get ( (AB)C)^T= (C^T) (AB)^T= (C^T) (B^T) (A^T).
