HOW TO GENERATE SQUARE PULSE

hi everybody,

I want to generate square pulse with different interval and the interval is random. in my case i have 1.2s 7 times,2.4s 7times and 3s 6times which will create 20 square pulse. the width is 0.07s.

anyone can help me? thanks.

If you have signal processing toolbox, use pulstran

EDIT

Amp=1   % Pulse amplitude
Wd=0.07   % Pulse width
sp=[1.2 2.4 3];
fr=[7 7 6];
spac_vect=cumsum(cell2mat(arrayfun(@(x,y) x*ones(1,y),sp,fr,'un',0)))
amp_vect=Amp*ones(1,numel(spac_vect)) % vector of amplitudes
t=linspace(0,max(spac_vect),1000) % time vector
d = [spac_vect;amp_vect]';
y = pulstran(t,d,'rectpuls',Wd);
plot(t,y)

I had used pulstran but the graph seems not like what I want.
