How to do an average alarm???????

Average alarm. When the average of the certain values in every 5 seconds goes ABOVE a selected threshold it says 'warning'

how do I do this in matlab?

thanks

load('matlab.mat')

figure

plot(matlab.Time,y)

title('Instant alarm')

hold on

y=average(time:5000+time);

for time=1:length(matlab.Time)

if y>=23

disp=('Warning, temperature too high!');

else

disp=('Normal temperature!');

end

end
