use stem() instead of plot() and you'll get it as shown in your image.

n=-10:10; % E.g. use any space
N1 = 2;   % E.g. set up at any value
x = zeros(size(n));
for jj=1:numel(n)
    if abs(n(jj))<=N1
    x(jj)=1;
    else
    x(jj)=0;
    end
end
stem(n, x)
title('\delta function'), shg

Hi,

here is one of the possible solutions:

n=-10:10; % E.g. use any space
N1 = 2;   % E.g. set up at any value
x = zeros(size(n));
for jj=1:numel(n)
    if abs(n(jj))<=N1
    x(jj)=1;
    else
    x(jj)=0;
    end
end
plot(n, x, 'k-', 'linewidth', 2), grid on
title('\delta function'), shg

Good luck.

tnx for answering . but the shape is not correct:

correct shape is :

take this solution

n = -5:1:5;
 s = zeros(size(n));
 for i = 1:length(n)
      if n(i)< -2
           s(i) = 0;
           elseif -2<=n(i)& n(i)<=2
            s(i) = 1;
      else
             s(i) = 0;  
      end
 end
 stem(n,s,'black','Linewidth',1.5), grid on
