matlab connect 4 game

I am making a connect 4 game using matlab and have gotten stuck. This is what i have so far. Any help would be appreciated.

    figure('Units','normalized','Position',[.2 .2 .6 .6], ...
           'Name','Connect Four','Color','w');
     axes('Units','normalized','Position',[.1 0 .8 .8], ...
          'Color','y','LineWidth',1,'Box','on');
     set(gca, 'XTick',[],'YTick',[],'XLim',[0,160],'YLim',[0,160]);
     hold on;
     for row = 1:7
         for col = 1:7
             board(row,col) = plot( col*20,row*20, 'wo','MarkerSize',30,...
                                    'LineWidth',.5,'MarkerFaceColor',[1 1 1]', ...
                                    'MarkerEdgeColor', [0 0 0]);
          end
      end

Where exactly are you getting stuck? Are you looking to implement callbacks to provide user interaction with your game? If so, please see
