Are you trying to create a row vector with all the different combinations of q1, q2, q3, and q4?
If so:
q1=11; q2=22; q3=33; q4=44;
a = [q1 q2 q3 q4];
b = reshape(a(perms(1:length(a)))',[1,numel(perms(1:length(a)))]);
If you would rather have a matrix of the different combinations, then:
b = a(perms(1:length(a)));
Or, if the order of b is really as you describe above, then use b as indices to a:
b = [1 2 3 4 2 4 3 1 2 1 3 4 3 2 1 2 3 4 1 3 2 4];
c = a(b);
