put values from -6 to 6 in n and change value of k according to n. x[-6]=4 ,x[-5]=2,and change values by simply puting values in question.

Hi,

the original picture has a file size of 5MBytes.
This picture has a filesize of 0.034MBytes

Mind that edaboard is an international forum and there are regions with low internet bandwidth

Generally it´s no good idea to take a high resolution photo from a computer monitor. It just gives huge file size with low quality. Better use the screenshot buttons of your keyboard (or other OS screenshot functions) and use .PNG file format.

This is my guess attempt:

Code:
clc;clear;
for n = 0:12
sum = 0;
for k = -6:5
if n < 3*k
u1 = 0;
else
u1 = 1;
end
if n < 4+3*k
u2 = 0;
else
u2 = 1;
end
sum = sum + (u1 - u2);
end
y(n+1) = 2*sum;
end

x = -6:6;
stem(x,y)
