Given 2 3D arrays, A and B, where A(:,:,i) and B(:,:,i) are i 2D matrices, multiply A(:,:,i)*B(:,:,i) without the use of a for loop.

More an experiment in coding than a practically useful piece of code, the goal was to derive an efficient method for multiplying many matrices together without the use of computationally expensive for loops.

Some applications include optical flow algorithms and image processing.
