Hello Goodnight.
I have 3 vectors that will constantly be changing the value of their elements. But the vector with the element greater than the elements of the other two vectors will be chosen. For example, of these three vectors the vector C would be chosen, since it has as element 18 and is the largest of the elements of the three vectors. The complete vector C will be chosen
A = [12 3 4 5 6]; B = [3 15 7 6 4]; C = [9 1 18 2 7];
In another combination it could be vector A or B depends on the maximum value of its elements.
How do I select the complete vector that contains at least one greater element than the other two?
Greetings and thanks.

A=[12 3 4 5 6];
B=[ 3 15 7 6 4];
C=[ 9 1 18 2 7];
R = [A(:);B(:);C(:)];
n = numel(A);
ii = ceil((1:3*n)/n);
[~,i1] = max(R);
out = R(ii == ii(i1));
or just
R = [A(:),B(:),C(:)];
[~,ii] = max(max(R));
out = R(:,ii);

If you can combine the three vectors in a single matrix R (say), you can find the max value of the matrix and then find which row it belongs to.
Max_value = max(max(R)) % to find max value
[Row_Id,Clmn_Id] = find(R==Max_Value)
Row_Id and Clmn_Id will give you the position of the value in matrix
