QUESTION- Function for Shifted Unit Step Sequence:

u[n − n0] =
1, n ≥ n0
0, n < n0
over the n1 ≤ n0 ≤ n2 interval.
function [x,n] = stepseq(n0,n1,n2)
% Generates x[n] = u[n − n0], n1 ≤ n ≤ n2
n1 = -7
n2 = 6
n0 = input('Enter desire value for shift ')
[z,v] = stepseq(n1,n0,n2)
stem(v,z)
function [y s] = stepseq(n1,n0,n2)
x = n1:n2
n3=-n1
y = [zeros(1,n3) ones(1,n2+1)]
s = x+n0
