I'm creating a code using Gauss-Seidel method. I'd like to create a vector with the answers of the iterations. How can I do that?
My work:
Ybus1 = [3.73-49.72i 0 0 0 -3.73+49.72i];
Ybus2 = [0 2.68-28.46i 0 -0.89+9.92i -1.79+19.84i];
Ybus3 = [0 0 7.46-99.44i -7.46+99.44i 0];
Ybus4 = [0 -0.89+9.92i -7.46+99.44i 11.92-147.96i -3.57+39.68i];
Ybus5 = [-3.73+49.72i -1.79+19.84i 0 -3.57+39.68i 9.09-108.58i];
Ybus = [Ybus1; Ybus2; Ybus3; Ybus4; Ybus5];
Vi = [1;1;1.05;1;1];
pk = [0 -8 4.4 0 0];
qk = [0 -2.8 0 0 0];
%% ********Gauss-Seidel********
N = size(Ybus,1);
for k = 2:N;
Vk = Vi(k);
S1 = 0;
S2 = 0;
F1 = Ybus(k,k);
for n = 1:k-1
S1 = S1 + (Ybus(k,n))*(Vi(n));
end
for n = k+1:N
S2 = S2 +(Ybus(k,n))*(Vi(n));
end
for iter = 1:100
F2 = (pk(k)-(qk(k)*1i))/conj(Vk);
Vk = (F2-S1-S2)/F1
end
end

Subscript them appropriately:
for iter = 1:100
F2(k,iter) = (pk(k)-(qk(k)*1i))/conj(Vk);
Vk(k,iter) = (F2-S1-S2)/F1
end
I’m not certain what you want to do, so it may be necessary for you to change the subscripts get the result you want. However that’s the general approach.

For example:
For k = 2, I find an answer. For k = 3, I find another answer...
I want to place the results for k = 2...3...4...5 in a vector
I hope you inderstood and can help me.
Thanks!

My code produces a matrix where the rows are over ‘k’ and the columns are over ‘iter’. My code will do what you want. You simply need to address the matrix correctly to get the result you want.
