i am doing a recognition system where i need to locate the minimum value for each row from the 40 by 40 matrices..i now can produce the list of minimum value from each row using this code.. A=min(euc,[], 2); but i still want it to show the minimum number produced is from which column (index number).. how do i write it?
best regards, farah

K = rand(5) ;
[val,idx] = min(K,[],2) ;
r = [1:size(K,1)]' ;
% positions
[r idx]
