Yes, you would get a different answer as you calculated different values. Which one is more accurate? Maybe the one with less looping, as more FP ops causes more rounding.
WebIf the product of two square matrices, P and Q, is the identity matrix then Q is an inverse matrix of P and P is the inverse matrix of Q. i.e. PQ = QP = I. The inverse matrix of A is denoted by A-1. (read as “A inverse”) AA-1 = A-1 A = I. Note that the inverse of A-1 is A. Example: Given that B is the inverse of A, find the values of x and ...
