Re: Dot product of three matrices

I guess I'm a little rusty in vector math, but can anyone tell me what the dot product of three matrices means? (i.e. is there a geometric interpretation?) And in what field of study does it come in handy?

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.	[reply] [d/l]

Is he? `$sum += $$x[$i] * $$y[$i] * $$z[$i];` [download] 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 :-)	[reply] [d/l]
