QUESTION- Function for Shifted Unit Impulse Sequence:

δ[n − n0] =
1, n = n0
0, n 6= n0
over the n1 ≤ n0 ≤ n2 interval.
function [x,n] = impseq(n0,n1,n2)
% Generates x[n] = δ[n − n0], n1 ≤ n ≤ n2
n1 = -10
n2 = 12
is = 2
[z,v] = impseq(is, n1, n2)
stem(v,z)
function [y,x1] = impseq(n0, n1, n2)
n3 = - n1
x = n1:n2
x1 = x + n0
y = [zeros(1,n3) ones(1,1) zeros(1,n2)]
