I have a vector of 1 column and a matrix of 5 x5, what I need to do is, assing 1 number of P to one numer of time in the first row, like number 1 to 1.7597 and 2 to 2.1777, is like colum per row but I need to assing it randomly, the number 1 have 5 changes to pick a number of the firts row, the number 2 have 5 changes of the row 2. How can I do this? I'm using matlab 2010
P =
1
2
3
4
5
time =
1.7597 1.6340 1.7157 1.6738 2.0185
2.3452 2.1777 2.2866 2.2308 2.6901
3.1412 2.9169 3.0627 2.9880 3.6032
2.8993 2.6922 2.8268 2.7579 3.3256
4.5961 4.2678 4.4812 4.3719 5.2720

Try this:
a=eye(5);
b=randperm(5);
c=a(b,:);
time(logical(c))=P;

@Ami, You need to clarify your comments. Reading your original question, you want to put P(1) into the first row of time randomly, P(2) into the second row of time randomly, etc. My code did that. Are you asking a separate question?
