I have a matrix i want to do non dominated sorting of the matrix and want to give the rank of the each row

Based on the value of Column f1 and f2 i want to make a new column named rank .Here the condition is both f1 and f2 column values are minimum and at the end I want to get the result

Thanks in Advance .

Hi

You can use the nondominatedsort function from the Multi-Objective Optimization (MOO) Toolbox to perform non-dominated sorting on a matrix. Here's an example of how you can do it:

% Add the MOO Toolbox to your MATLAB path
addpath('');
% Perform non-dominated sorting
fronts = nondominatedsort(matrix);
% Calculate the rank of each row
rank = zeros(size(matrix, 1), 1);
for i = 1:numel(fronts)
    rank(fronts{i}) = i;
end
% Display the rank of each row
disp(rank);
