g1 = [1 1 1 1 1 1 1 1 1 1];
g2 = [1 1 1 1 1 1 1 1 1 1];
%disp(g1);
for i = 1:20
y1 = xor(g1(3),g1(10));
y2 = xor(g2(2),g2(3));
y21=xor(g2(6),y2);
y22=xor(g2(8),y21);
y23=xor(g2(9),y22);
y24=xor(g2(10),y23);
y3 = xor(g2(2),g2(6));
output= xor(g1(10),y3);
disp(output);
%put in other xor commands
g1(1) = y1;
g2(1) = y24;
B = circshift(g1,[0 1]);
C = circshift(g2,[0 1]);
end
disp(g1);
disp(g2);
above is the code i hve written as well as the prompt for the project. I belive I have the code written correctly, because I get the correct answer when I run through the code once. When i try to run the for loop 20 times I get the same answer as if there isn't a for loop. I believe the issue has something to do with my for loop. Id greatly appreciate any help, cheers!

Well, you define B and C but never use them anywhere, so that could explain why iterations after the first don't matter.
Try it like this (my best guess):
g1 = [1 1 1 1 1 1 1 1 1 1];
g2 = [1 1 1 1 1 1 1 1 1 1];
%disp(g1);
for i = 1:20
y1 = xor(g1(3),g1(10));
y2 = xor(g2(2),g2(3));
y21=xor(g2(6),y2);
y22=xor(g2(8),y21);
y23=xor(g2(9),y22);
y24=xor(g2(10),y23);
y3 = xor(g2(2),g2(6));
output= xor(g1(10),y3);
disp(output);
% g1(1) is y1, and the other elements shift by one, discarding g1(end)
g1 = [y1 g1(1:end-1)];
% g2(1) is y24, and the other elements shift by one, discarding g2(end)
g2 = [y24 g2(1:end-1)];
end
disp(g1);
disp(g2);
