Find the maximum value in different vectors and from which vector is it?

I have the following vectors:

v1 = [1 1 3 3 1]

v2 = [2 2 1 1 2]

v3 = [3 3 2 2 3]

I want to compare each element of all the vectors and determine which one is the highest and from which vector it corresponds.

Im guessing I will have some kind of indexing like this:

v1 =[False False True True False]

v2= [False False False False False]

v3=[True True False False True]

Any suggestions?

Thanks

max_val = max([v1, v2,v3]); % or max_val = max([v1(:);v2(:);v3(:)]);
v1 = v1 == max_val;
v2 = v2 == max_val;
v3 = v3 == max_val;

Thanks for your answer. This is a good solution for finding the max value of all the vectors, but what I'm looking for is comparing the firsts elements of the 3 vectors, determine the highest value and from which vector correspond and so on with all of the elements of the 3 vectors.

v = [v1; v2; v3];
max_val = max(v);
v = v == max_val;
v1 = v(1, :);
v2 = v(2, :);
v3 = v(3, :);

Am I correct now?

Yes, it worked perfectly.

Thanks a lot
