Ran in:
LD = [1 2 0.004 1 0.05i 0 100

PTR= 150e3/110;
CTR= [240 240 160 240 240 240 160 240 160 240 240 240 240 160];
for i=1:7
% for n=8:14
z(i,1)=(LD(i,3)+LD(i,5))*LD(i,7);
% z(n,1)=(LD(i,3)+LD(i,5))*LD(i,7);
% end
theta = angle(z(i,1));
z = abs(z)
end
z = 5.0160
z = 2×1
5.0160 5.0139
z = 3×1
5.0160 5.0139 4.5217
z = 4×1
5.0160 5.0139 4.5217 4.5277
z = 5×1
5.0160 5.0139 4.5217 4.5277 4.5261
z = 6×1
5.0160 5.0139 4.5217 4.5277 4.5261 4.5174
z = 7×1
5.0160 5.0139 4.5217 4.5277 4.5261 4.5174 5.0249
% for i= 1:14
% zsz1(1,i) = ((z(i,1))/(cos((theta(i,1)-45)*pi/180))*(CTR(1,i)/PTR));
% end
i need my loop to repeat again i want answers to be exactly like the first seven z(i,1)...thank u

Do you mean to repeat the loop infinitely unless broken on Ctrl+C?

5.0139
4.5217

If you simply want to repeat the loop while printing out exactly the same values each time, then do this:
for k = 1 : 2
for i=1:7
z(i,1)=(LD(i,3)+LD(i,5))*LD(i,7);
theta = angle(z(i,1));
z = abs(z)
end
end

While you could, why not just duplicate the array as many times as needed once it's been generated --
z=repmat(z,2,1);

well thank u all ...first why do another loop?the ans is i have to calculate line impedance so i have 1 to 2 line and 2 to 1 line ..thats why i need this to be repeated as u see here
%n fromline toline impedance
B=[1 2 1 1 z(1)
2 1 3 2 z(2)
3 3 4 3 z(3)
4 4 5 4 z(4)
5 5 6 5 z(5)
6 6 2 6 z(6)
7 6 1 7 z(7)
8 1 2 1 z(1)
9 3 1 2 z(2)
10 4 3 3 z(3)
11 5 4 4 z(4)
12 6 5 5 z(5)
13 2 6 6 z(6)
14 1 6 7 z(7)];

If you have the left 4 columns of B already, you could just tack on two copies of z:
z = 1:7;
B=[1 2 1 1
2 1 3 2
3 3 4 3
4 4 5 4
5 5 6 5
6 6 2 6
7 6 1 7
8 1 2 1
9 3 1 2
10 4 3 3
11 5 4 4
12 6 5 5
13 2 6 6
14 1 6 7];
z2 = [z(:); z(:)];
B = [B, z2]
