If you have n vectors with the same size, you can create one matrix nx2. It's not a good idea to create those vectors, just use a matrix nx2, it contains all your vectors.

a=[10 20]
b=[100 30]
c=[5 2]
% create a matrix M
M=[a;b;c]
c2=M(:,2)  % The second column
[max_value,index]=max(c2)

i want it for great population like 1000 vectors...

Ok, you can create a 1000x2 matrix

how? i write this vectors for 1000 times in the M ?

Did you read the FAQ link I posted?

Best solution: do not use 1000 different vectors to start with.
