Hi all,
Thank for the help in advance.
I have a matrix in dim. of 972 (rows) * 715 (columns) I want to make an average of each row then divided by the num of columns. the final matrix should be 972*1 could any one help me with this? in for loop (because I will apply it in addition for other matrices)
thank you so much.

Taking your question literally would yield:
dummy = rand(972,215);
result = mean(dummy,2) ./ size(dummy,2)

doc mean you can specify the dimension there and get what you want.
A = rand(972,715) ;
M = mean(A,2) ;
