i have several thousand Cartesian coordinated separated into two groups. The location of the two groups are relative to each other. I have created a new model for one of the groups and I would like to update the coordinates of one group but keep its same relative location to the first group. How do I systematically transpose one groups coordinates over another groups coordinates. (Please if possible be specific. I really need to do this not just think about possible solutions.)

i'm looking for a way to find a vector x that i can find inside old C which I can multiply by the matrix new C (where Cs are not perfectly equal) but the results only need to be accurate to a few degrees of freedom. I just don't know how to find this matrix. :)
Since the matrix which needs to be chagned is set at 0 as the first element. I could add the minimum vector to each element and it gets me to the begining of the proposed position. Now I need to rotate the plot so that it is oriented the same as before.
How do I calculate the rotation change needed and change the rotation of several points?
