why this loop is not working? Actually p_j value is not changing why?

n = input('please enter number of strips :');
for i = 1:n
for j = i
p_i = 0
p_j = p_i + D/(2*n)
epsilon_ci = (epsilon_max/xu)*(xu-p_j)
sigma_ci = 0.45*fc*[2*(epsilon_ci/0.002)-(epsilon_ci/0.002)^2]
p_i == p_j;
end
end

"why this loop is not working?"
It is working.
"Actually p_j value is not changing why?"
Because you are over-writing p_j with every iteration.
It is difficult to make any suggestions as it is not clear what you are trying to do. Format your code properly, mention values of variables and specify what you want to do with this code.

Instead of p_j write p(j)

Ran in:
n = 10;% e.g. input number
epsilon_ci = 0.001;
epsilon_max = 0.01;
xu = 2;
fc = 100;
D = 1.1;
p_i = 0; %outside for loop
for i = 1:n
p_j(i) = p_i + D/(2*n);
epsilon_ci = (epsilon_max/xu)*(xu-p_j(i));
sigma_ci = 0.45*fc*(2*(epsilon_ci/0.002)-(epsilon_ci/0.002)^2);
p_i = p_j(i); % assign new p_i
end
p_j
p_j = 1×10
0.0550 0.1100 0.1650 0.2200 0.2750 0.3300 0.3850 0.4400 0.4950 0.5500
