I have written this
X =rand (4,2)
t= size (X);
permlimit = 100;
M2 = zeros([permlimit, t(2)]);
for ii = 1 : permlimit
for jj = 1 : t(2)
M2(ii,jj) = X(randi(t(1)),jj);
end
end
But in out put I have some similar result, I do not want to have, how to prevent having them ? for example I will have in my results M2 =
0.3897 0.1171
0.3335 0.1604
0.3335 0.1171
0.3337 0.1604
0.3897 0.5503
0.3337 0.1171
0.3897 0.1604
0.3337 0.1604
0.3337 0.1604
As you see some of results are the same like
0.3337 0.1604
0.3337 0.1604

Number permutation for matrix with size 4x2 in your case: 16, ie will repeated rows
