in thread Dot product of three matrices

I think by "three matrices" OP meant "two vectors" .. it's just that instead of having $Ax,$Ay,$Az and $Bx, $By, $Bz, OP is instead passing [$Ax, $Bx], [$Ay,$By], [$Az,$Bz] to his sub.

    $sum += $$x[$i] * $$y[$i] * $$z[$i];

    The above code implies bad things but he is in fact calculating the dot product of 3 vectors that are 2D. To sum it up: not the clearest code ever :-)
