WebWant to see another example? Here it is for the 1st row and 2nd column: (1, 2, 3) • (8, 10, 12) = 1×8 + 2×10 + 3×12 = 64 We can do the same thing for the 2nd row and 1st column: (4, 5, 6) • (7, 9, 11) = 4×7 + 5×9 + 6×11 = 139 And for the 2nd row and 2nd column: (4, 5, 6) • (8, 10, 12) = 4×8 + 5×10 + 6×12 = 154 And we get: DONE! Why Do It This Way? WebJan 29, 2015 · where A is 4x4, M is 3x3, b is 3x1, and the bottom row is (0,0,0,1), then inv (A) = [ inv (M) -inv (M) * b ] [ 0 1 ] Depending on your situation, it may be faster to compute the result of inv (A) * x instead of actually forming inv (A). In that case, things simplify to inv (A) * [x] = [ inv (M) * (x - b) ] [1] = [ 1 ]
