MATLAB: Check for identical maximum values in an array

multiple max values in an array

Hi guys, I have a matrix, A = [2 4 1;8 3 2;8 8 6;4 5 3] As seen, the above matrix has more than one maximum values. How do i write an if statement testing for multiple maximum values? That is: if (code) % if more than one maximum value exists; …; % do … end

Best Answer

"if more than one maximum value exists in the array pick the first max value and display it's index"
idx = find( A(:) == max(A(:)) );
if length(idx) > 1
  disp(idx(1))
end
