function d = ddv(varargin)% DDV - Constructor for the class ddv, a sub class of the gen class.% The constructor can be called in two ways:%% ddv('name',value_1,value_2,etc..) where 'name' is a string identifying% the variable and value_1, value_2 etc. are the possible values that% the discrete variable can assume.  %% ddv('name',[value_1 value_2 etc..]) here 'name' is as before but% the possible values are suppplied in a vector.  % % There is no need  for supplpiyng the coding bits since this is% determined by the possible values that the variable can assume.    %% Calling the constructor without any argument creates an "empty" variable.%% See also CDV,CHROM,UI_GEN,UI_CHROMswitch nargin case 0  pointer=0;  d=struct('ddv_val',[]);  d = class(d,'ddv',gen); case 1  if isa(varargin{1},'ddv')    d=varargin{1};  else     error('wrong argument')  end case 2  if ~isa(varargin{1},'char')    error('You must specify the the id as the first argument')  else     for k=1:length(varargin{2})      ddv_val(k)=varargin{2}(k);    end    d=struct('ddv_val',ddv_val);    d=class(d,'ddv',gen(varargin{1},nextpow2(ddv_val)));  end otherwise  if ~isa(varargin{1},'char')    error('You must specify the the id as the first argument')  else     for k=2:nargin      ddv_val(k-1)=varargin{k};    end    d=struct('ddv_val',ddv_val);    d=class(d,'ddv',gen(varargin{1},nextpow2(ddv_val)));  endend
