I want to find value of r for corresponding value of OG. but I am not able to get output. I recieved" Error using horzcat Dimensions of matrices being concatenated are not consistent". How to solve this problem. PLz help

Substitute OG at the end into the equation:
OGnum = 2:2:10;
W = [];
for i=1:numel(OGnum)
AUU = subs(AU,OG,OGnum(i));
r = solve(AUU==0,AX0)
W = [W,r]; % or maybe W = [W;r];
end
