Hi, Minhaz Parveez
As per my understandig you want to calculate the mean of each coloumn of the matrix. By default MATLAB fuctions work on coloumns therefore you can use the mean function directly. Please refer to the code below. Hope it helps!
X = [5 2;5 6;8 8]
X = 3×2
5 2 5 6 8 8
mean(X)
ans = 1×2
6.0000 5.3333
