3 Dim matrix question and problem

I want to perform matrix math using a varible in three dim as a function of time Axyz(t)=multiple functions with x, y, z dim.  Is there a way in Mathcad 15 to represent this (image a 3 dim cube with a particle in the center and or at each of the corners, as a function of time, I use field theory to alter each particle state, and thus effecting the nearest particle - one time unit later - as it ripples through each "cell" in the cube????)
