Matrix loop multiplication warning

Hello,
I have this code:
n=1;
Eout=zeros(4096,2);
while n<=4096
E=[Eopt(n); 0]; coupler=[sqrt(0.9) 1i*sqrt(0.1);1i*sqrt(0.1) sqrt(0.9)];
Eout(n)=coupler*E;
n=n+1;
end
I would like to have the various n results from Eout (a 2x1 matrix) in 4096x2 matrix. However, when i run this code this warning appears:
??? In an assignment A(I) = B, the number of elements in B and I must be the same.
Error in ==> Sim42 at 62
What should i do?
Thanks

You should add an extra dimension to the ‘Eout’ assignment:
Eopt = randi(100, 4096, 1); % Create Data
n=1;
Eout=zeros(4096,2);
while n<=4096
E=[Eopt(n); 0];
coupler=[sqrt(0.9) 1i*sqrt(0.1);1i*sqrt(0.1) sqrt(0.9)];
Eout(n,:)=coupler*E;
n=n+1;
end
Then it works!
