How to find maximal values in matrix?

• I have a matrix: A =[1, 128; 2, 300; ...;20, 500;...;99, 10; 100, 0];
• the row I need to extract be B=[20,500], with 500 is maximal value of 2sd colum.

How I can do?

This works:

A =[1, 128; 2, 300;20, 500;99, 10; 100, 0];
B =  A(A(:,2) == max(A(:,2)),:)

B =

      20   500

It compares the second column of ‘A’ with the maximum of the second column of ‘A’, and then selects that entire row.
