Combining files and mapping them using x and y coordinates

I have conducted an experiment that includes four different participants. I basically measure two different variables "E" and "R" at different locations identified by x and y coordinates. So, I have four different files one for each participant. What I want to do is to compare the x and y coordinates for the different participants, if they are equal(which means at the same location) I need to get the average of "E" and "R", if they are not at the same location, just store the E and R values as it is.

In the end I need one matrix showing one value for each of E and R at all different locations.

How can I do that in Matlab?
