I have a table with 10 variables and 3 other descriptor variables (Subnum, Condition , Trial ). So each condition has 4 trials. I want to create means across trials per Subnum. So it would be 20 means per Subnum [2 per each variable becasue of the 2 conditions]. I would be perfect if I can create 2 seperate matricies per Subnum with a row of 10 means since I have to input that variable into another script. I'm new to MATLAB so I appreciate any help.
