Use randperm to get a sequence of integers with no repetitions:

>> randperm(9)
ans =
   9   6   5   8   3   7   1   4   2

If you want a matrix where each row has unique numbers, then you can use a loop:

R = 3;
C = 5;
mat = NaN(R,C);
for k = 1:R
    mat(k,:) = randperm(C);
end

which gives:

>> mat
mat =
 3   4   1   5   2
 4   1   2   5   3
 4   5   2   1   3

Thanks but i'have forgotten to precise that the matrix elements should be interger.
