find distance between points and select longest 2 lines in matlab

main.m
% Define two sets of points
set1 = [1, 2; 3, 4; 5, 6];
set2 = [2, 3; 4, 5];

% Calculate the distance matrix between the points
dist_matrix = pdist2(set1, set2);

% Display the distance matrix
disp(dist_matrix);

10 lines

main.m
% Define a set of lines as a matrix
lines = [1, 2, 3, 4; 5, 6, 7, 8; 9, 10, 11, 12];

% Calculate the length of each line
line_lengths = sqrt((lines(:, 3) - lines(:, 1)).^2 + (lines(:, 4) - lines(:, 2)).^2);

% Sort the lines by length
[sorted_lengths, sorted_indices] = sort(line_lengths, 'descend');

% Select the longest two lines
longest_lines = lines(sorted_indices(1:2), :);

% Display the longest two lines
disp(longest_lines);
