I have a 9000 by one Matrix.As an Example considering the following
X Y Z P
5 5 5 900
5 5 10 800
5 5 15 1200
5 10 5 300
5 10 10 560
5 10 15 900
I want compute average P at each Y, that means all values of P when Y is 5.Similary when y is 10....It is just a example.Next x goes to 10 and same varies

findgroups() and then splitapply()
However, if your array is as regular as it looks, you should probably just reshape and mean() along the appropriate plane (you might need a permute() in there, and maybe two rounds of reshape())
