I have M=2 S=2 and having 4 possible combination of these two. Need to form a matrix from these four possibilities a= [1 1 2 2;1 2 1 2]. so i want to make a generic code using for loop that may be valid for every value of M and S....Thanks

M=2; S=[1,2];pos=size(S,2)^M;for i=1:M for j=1:pos X(i,j)=S(i) end end

This is not generic code...secondly the result i want is not perfect for the scenario i attached a pic of the scenario but need a generic code that will be valid for increasing M and s

It's not clear. How does your desired output look like?

Desired output should be 2*4 matrix for the above scenario.

[KL]

M = 2;
S = [1,2];

S1 = reshape(repmat(S,size(S,2),1),1,size(S,2)*M);
S2 = repmat(S,1,size(S,2));

X = [S1; S2];
