set.m

一些用matlab编写的经典遗传算法算例 挺有用的

function g = set(gen,varargin)
% SET - This function gives acces to the fields in the gene. 
% Any number of valid properties can be set with one function
% call.  The syntax for calling the function is:
% set(gene,'property',value,'property',value,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 set(gene)

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

  if ~or(or(tst==3,tst==5),tst==7)
    error('wrong number of arguments')
  else
    for k=1:2:tst-1
      switch varargin{k}
       case 'name'
	gen.name=varargin{k+1};
       case 'value'
	gen.value=varargin{k+1};
       case 'bits'
	gen.bits=varargin{k+1};
       case 'dna'
	gen.dna=varargin{k+1};
     otherwise
      error('Unknown method')
      end
    end
    g=gen;
