getting an entire row containing the max value in column n in a matrix

Hello everyone,

here is my problem :

I have lots of files containing a matrix of the form N x 3 elements ; and I would like to extract the entire row containing the maximum value of the second column so I can write them in a new matrix.

I tried the MAX function but it gives me the maximum value of each row...

Any help ? Thank you !!

N=5
out=zeros(10,3);
for k=1:10
    A=rand(N,3);
    [~,idx]=max(A(:,2));
    out(k,:)=A(idx,:);
end

Azzi gave you code for extracting the row that has the max in the array A. To get the arrays "A" from all your various files, see the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F
