Accepted answer

nHours = 4; %number of hours Ts = 15; %sampling period [s]

data = [3793.197... %your data is 960x1 size %data = rand(nHours*3600/Ts,1); %test data (4hours*3600second/15second)

meanT = 10*60; %test period [s] matrix = reshape(data,3600/Ts,nHours); out = mean(matrix(1:meanT/Ts,:));

A=rand(720,1);

A=reshape(A,240,3);

A_OUT=mean(A(1:40,:))
