% RESPLOT.M       (RESult PLOTing)
%
% This function plots some results during computation.
%
% Syntax:  resplot(Chrom,IndAll,ObjV,Best,gen)
%
% Input parameters:
%    Chrom     - Matrix containing the chromosomes of the current
%                population. Each line corresponds to one individual.
%    IndAll    - Matrix containing the best individual (variables) of each
%                generation. Each line corresponds to one individual.
%    ObjV      - Vector containing objective values of the current
%                generation
%    Best      - Matrix containing the best and average Objective values of 
%                each generation, [best value per generation,average value 
%                per generation]
%    gen       - Scalar containing the number of the current generation
%
% Output parameter:
%    no output parameter
