MULTIDIMENSIONAL ARRAY COORDINATES AND POINTS

hi everybody, this is the description of the problem, i have two matrix: 1) the first one is a matrix that describe coordinates(x,y,z) of a series of points 2) the second one is a matrix that have in every lines a series of points the question is: is that possibile to create a multidimensional array that have in every point of matrix 2 the relative coordinate of matrix 1?

i'll show you and example: for example let's take a line from matrix 2 --> 2,5,6,9 the relative coordinates in matrix 1 of those points are: line 2---->x=4,y=9,z=10 . . . line 5---->x=0,y=10,z=4 exc... Thank you to everyone who have time to answer!
