Not sure if you understand the meaning of {} in MATLAB. It is used to reference cell array. Your example data indicates no need of it. Please do not use it unnecessarily because it might confuse readers regarding your data structure.

If you do not have to use a for loop you can just do:
I = G(:, 1:2)
but if you have to use a for loop:
for ii = 1:size(G, 1)
I(ii, 1:2) = G(ii, 1:2);
end

Assume the element in I is the first two columns of the element in G.
G=[1 0 1;1 0 0;0 0 1;1 1 1];
[M,N]=size(G);
I=zeros(M,2);
for k=1:size(G,1)
I(k,:)=G(k,1:2);
end
Without for-loop, you can do.
I=G(:,1:2)

for j1 = 1:size(I,2)
I(:,j1) = G(:,j1);
end

and I am giving a +1 to Fanqjun since he (assuming he) gave the same answer, and typed faster than me.
