sort.m

一些用matlab编写的经典遗传算法算例 挺有用的

function varargout = sort(chr)
% SORT - Sort in ascending order.  For a vector of chromosomes, sort(x)
%    sorts the objects of x in ascending order, with the respect to
%    the fitness of the chromosomes. 
%    [y i] = sort(x) also returns an index vector.
for k=1:length(chr)
  tmp(k)=chr(k).fitness;
end
[q ind]=sort(tmp);
varargout{1}=chr(ind);
varargout{2}=ind;
