unit step sequence

here's another one

function usts()

f=input('enter the sampling frequency= ');

l=input('enter the length of the sequence= ');

Ts=1/f;

n=1:l;

x(n)=ones(1,numel(l));

n=0:l-1;

stem(n*Ts,x,'fill');

title('unit step sequence');    

xlabel('time in secs');

ylabel('amplitude');
