dear all, my question is how do solve kronecker's product of a 10x10 matrix or any matrix size using nested loops rather than the conventional Kron function.
for eg,
aa=round(rand(10,10)*10-5)
bb=round(rand(10,10)*20-10)
what do i write in the script to solve the multiplication of aa*bb using kroneckers rule.
thanks!

you can do it as follows(if you have square matrices of same size):
A = round(rand(10,10)*10-5);
B = round(rand(10,10)*20-10);
for i = 1:size(A, 1)
for j = 1:size(A, 2)
AB{i, j} = A(i, j) * B;
end
end
AB = cell2mat(AB);
disp(AB)
Good luck!

yes it works now! and I'm guessing that when i change the first value of the matrix, it would also be able to calculate no matter what the size of the matrix is? thanks heaps!
