I process the signal with the findpeaks function, it gives the position numbers of these peaks, and now I need to calculate how many peaks are in the time interval.
loc=[2 3 7 8 9 10 25 26 27]
intervaltime=6
%ans= [2 4 0 0 3] % my length vector is 100  
%% zeros because there was nothing in the interval 12-18 and 18-24
Thanks in advance

				Exactly which elements do you consider below to be "peaks"?  And where is your call to findpeaks()?
loc=[2 3 7 8 9 10 25 26 27];
intervaltime=6;
%ans= [2 4 0 0 3] % my length vector is 100  
%% zeros because there was nothing in the interval 12-18 and 18-24
plot(loc, 'b.-', 'MarkerSize', 30, 'LineWidth', 2);
grid on;
title('Peak Detection');
xlabel('Index')
ylabel('loc Signal Value')

        Probably not the best way to go but I got this:
location = [ 2 3 7 8 9 10 25 26 27];
intervaltime = 6;
for i = 1:5
    result(i) = length(location(location < i*6));
    result(i) = result(i) - length(location(location < (i-1)*6))
end
