get.m

一些用matlab编写的经典遗传算法算例 挺有用的

function varargout =get(gen,varargin)
% GET - Returns the values of the design variable corresponding to
% the property list. Any number of properties can be returned with one
% function call. 
%   
% [val1 val2 etc...]=get(gene,'property','property',etc..).  
% The properties are:
%
% 'name' - the name of the variable
% 'value' - the value of the variable
% 'bits' - number of coding bits
% 'dna' - a vector containing the binary "dna"
% 'l_limit' - the lower limit for a cdv
% 'u_limit' - the upper limit for a cdv
% 'p_val' - the possible values for a ddv [val1 val2 etc...]
%
% to list the valid properties for a certain object use get(gene)

tst=nargin;
if tst==1
  fprintf('Valid properties:\nname \nvalue \nbits\ndna\n')
else

  if ~or(or(tst==2,tst==3),tst==4)
    error('bad number of arguments')
  end
  for k=1:tst-1
    switch varargin{k}

    varargout{k}=gen.name;
     case 'value'
      varargout{k}=gen.value;

    varargout{k}=gen.dna;
     otherwise
      txt=strcat('bad argument:',varargin{k});
      error(txt)
    end
