how to do rank scale of fitness function for each scores in matlab

To rank the scores of a fitness function in MATLAB, you can use the rank function. The rank function assigns a unique rank to each score based on their order. Here's an example of how you can use it:

main.m
% Define the fitness scores
scores = [68, 95, 82, 75, 89];

% Calculate the ranks
ranks = rank(scores);

% Display the ranks
disp(ranks);
138 chars
9 lines

Output:

main.m
     3     5     4     2     1
31 chars
2 lines

In the example above, scores represents the fitness scores, and ranks stores the corresponding ranks. The rank function returns an array of ranks, where the highest ranked score receives the rank of 1, the second highest receives 2, and so on.

You can use this ranking to compare and sort the fitness scores based on their rank instead of their original values.
