 INITialzation function for DOuble Integrator objdopi

 This function initializes the Double Integrator.

 Syntax:  [Chrom, VLUB] = initdopi(Nind, VLUB, method, TSTART, TEND)

 Input parameters:
    Nind      - Number of individuals
    VLUB      - Matrix containing the boundaries of the variables
    method    - (optional) method of simulation
    TSTART    - (optional) start time
    TEND      - (optional) end time

 Output parameters:
    Chrom     - Matrix containing the chromosomes of the current
                population. Each row corresponds to one individual's
                string representation.
    VLUB      - (optional) Matrix containing the new boundaries
                of the variables

function [Chrom, VLUB] = initdopi(Nind, VLUB, method, TSTART, TEND);

% Compute population parameters
   Nvar = size(VLUB, 2);
 
% Check input parameters 
   if nargin < 3, method = 1; end     % 1 - sim: simulink model
   if nargin < 4, TSTART = 0; end
   if nargin < 5, TEND   = 1; end

% Create population, this is for illustration, there is no real meaning
   Chrom = rand(Nind, Nvar);
   Chrom = (Chrom <  0.5) .* repmat(VLUB(1,:), [Nind, 1]) + ...
           (Chrom >= 0.5) .* repmat(VLUB(2,:), [Nind, 1]);
