i want to extract valid possibilities from matrix. A screenshot of that matrix is attached here.

I have

Meters= 2
Subcarriers=2
Power levels=[0.5,1]

I wanted to find the total possibilities.. (a picture of the matrix is attached which you can see)

Now i want to extract the valid possibilities which are satisfying our constraint..

that is we can't give same subcarrier to both Meters..

from Picture you will see that possibility 3 and possibility 4 are valid.. similarly poss. 7 poss. 8 and so on..

The following code give us the total possibilities which results i have attached in picture..

clc;clear all;close all;
M=2;
S=[1:2];
%r1=1;
v=0;
P=[0,0.5,1];
pos=(size(S,2)*size(P,2))^M;
m=pos/(size(S,2)*size(P,2));

for i=1:M
       r=2*(size(S,2)*size(P,2))^(M-i);
       r1=1;
    for j=1:(pos/m)
        for l=1:(size(S,2)*size(P,2))^i
            X(i,r1:r)=S(1,v+1);
            r1=r+1;
            r=r+2*(size(S,2)*size(P,2))^(M-i);
            v=mod(v+1,size(S,2));
        end
    end
end

for i=1:M
       r=(size(S,2)*size(P,2))^(M-i);
       r1=1;
    for j=1:(pos/m)
        for l=1:(size(S,2)*size(P,2))^i
            Y(i,r1:r)=P(1,v+1);
            r1=r+1;
            r=r+(size(S,2)*size(P,2))^(M-i);
            v=mod(v+1,size(P,2));
        end
    end
end

for i=1:M
    for j=1:pos
        Z(i,(2*j)-1)=X(i,j);
        Z(i,2*j)=Y(i,j);
    end
end
Z=double(Z)

Thank you

Try this,

 Z_re = arrayfun(@(a) [Z(:,a:a+1)],1:2:size(Z,2),'uni',0);
 Z_selected = cell2mat(Z_re(cellfun(@(x) x(1,1)~=x(2,1),Z_re)));
