median.m

一些用matlab编写的经典遗传算法算例 挺有用的

function m = median(chr)
% STD - Median value
%    For vectors, MEDINA(chr) returns the median of the members
%    in the population. For matrices, MEDIAN(chr) is a column vector
%    containing the median of each row
% 
% See also MAX,MIN,MEAN,STD
[m n]=size(chr);
for k=1:m
  for l=1:n
    fit(l)=get(chr(k,l),'fitness');
  end
  m(k,1)=median(fit);
end
