Unit step using MATLAB

In this section we will be learned how to implement unit step in MATLAB.

MATLAB code:

%unit impulse

n=-10:20

us=[zeros(1,10) 1 zeros(1,20)];

subplot(3,1,1);

stem(n,us);

title('unit impulse')

%delayed unit impulse

usd=[zeros(1,15) 1 zeros(1,15)];

subplot(3,1,2);

stem(n,usd);

title('delayed unit impulse')

%advanced unit impulse

usa=[zeros(1,3) 1 zeros(1,27)];

subplot(3,1,3);

stem(n,usa);

title('advanced unit impulse')

axis([-10 20 0 1.2]); %defining axis

OUTPUT:
