WebWe also note that A’A is not invertible (det = 0), and so we use AA T to calculate the pseudo-inverse (as expected since m < n). Finally, we see that AA + = I, as shown in range L18:N20. Note that while A + is a right inverse, it is not a left inverse (A + A ≠ I).

Web21 okt. 2010 · 1) For A and B to be invertible then they must live up to AB = I, which implies that either. AA^-1 = I if B = A^-1. Or if BA = I which implies that A = B^-1. 2) Hence then for the matrix product to exist then it has to live up to the row column rule. Then I choose A and B to be square matrices, then A*B = AB exists.
