I want to copy the rows of G1 to G2 in inner for loop but error occurs , please help

G1 = [1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1;
0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1;
0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1;
0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1;
0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1;

m=4;
r=4;
k=0;
n=2^m;
k=15;
for a=r:-1:2
M=factorial(m)/(factorial(m-a)*factorial(a));
G2 = zeros(M,n);
for o=1:1:M
G2(o,:) = G1(k,:);
k=k-1;
end
end

the first time through the loops, k = 15. but size(G1) is 11x16. So the first time you are effectively doing
G2(o,:) = G1(15,:)
which doesn't work. Maybe you meant this instead?
G2(:, o) = G1(:,15)

This this the complete code, value of a decrease , M is computed and G2 is generated having rows equal to M, than i want to copy G1 rows portion to G2 in each iteration of for loop, the complete code is given below G1 = [1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1; 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1; 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1; 0 0 1 1 0 0 1 1 0 0 1 1 0 0 1 1; 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1; 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1; 0 0 0 0 0 0 0 0 0 0 1 1 0 0 1 1; 0 0 0 0 0 0 1 1 0 0 0 0 0 0 1 1; 0 0 0 0 0 0 0 0 0 1 0 1 0 1 0 1; 0 0 0 0 0 1 0 1 0 0 0 0 0 1 0 1; 0 0 0 1 0 0 0 1 0 0 0 1 0 0 0 1]; m=4; r=4; k=0; n=2^m; for i=1:r k= k+factorial(m)/(factorial(m-i)*factorial(i));
end
for a=r:-1:2 M=factorial(m)/(factorial(m-a)*factorial(a)); G2 = zeros(M,n); for o=M:1:1 G2(o,:) = G1(k,:); k=k-1; end end

That doesn't change anything about my previous comment. at the conclusion of this section of the code
for i=1:r k= k+factorial(m)/(factorial(m-i)*factorial(i)) end
the variable k has the value 15. And G1 has size 11x16 = 11 rows and 16 columns.. So G1(k,:) is asking to access the 15th row of a matrix that has only 11 rows. You can't copy a row that doesn't exist.
