I have the following matrix
x =
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20
I would like to have 100 different permutation and in each I change randomly one variable of each row with others like this
1 7 13 4 5
then
11 5 4 19 2
and so on

It's getting clearer. The above seems clear but I'm not sure where [11 5 4 19 2] comes from in your first post. That is not in your list just now.

Mohommad, have I answered your question on the original thread?

Just set solutionLimit = 100, and it seems to solve this exact same question.

Stab in the dark:
sizeX = [4,5];
permlimit = 100;
X = reshape(1:prod(sizeX),fliplr(sizeX))';
Y = zeros([permlimit, sizeX(2)]);
for ii = 1 : permlimit
for jj = 1 : sizeX(2)
Y(ii,jj) = X(randi(sizeX(1)),jj);
end
end
disp(Y)
