y = randi(100, 1, 120); % assumed data of length 120
for ii = 1:4:length(y)
    values_4 = y(ii:ii+3);  % fou
    if mean(values_4) ~= 10 % assumed condition here
        % your operation
    else
        break;  % operation breaks here
    end 
end

sir thanku for your answer. There is a problem when running this program .

 for i=0:4:120
        for j=1:i
     
        end
end

while running this we get 1...4,1...8,....etc.

i want to get 1....4 then 5....8 like this.How to solve this
