  • A (-1) = (3) ,,,,,,, A (0) = (-4)
    ... (2) .. (5) ,,,,,,,,,,, (-2) .. (-6)

    A (-1 .. 0) = (3 ... -4) ======> AB = C => A = C . B^-1
    ... (2 .. -2) .. (5 .. -6)

    A = (3 ... -4) 1/2 (-2 ... 0)
    ...... (5 ... -6) ...... (-2 .. -1)

    A = 1/2 (-6 + 8 ....... 0 + 4)
    .............. (-10 + 12 .. 0 + 6)

    A = 1/2 (2 ... 4)
    ............. (2 .. 6)

    A = (1 ... 2)
    ...... (1 ... 3)

    A (4 ... 2) = (1 ... 2) (4 ... 2) = (4 + 0 ... 2 - 6) = (4 .... -4)
    ... (0 .. -3) .. (1 ... 3) (0 .. -3) .. (4 + 0 ... 2 - 9) .. (4 .... -7)
