%   This function does two things. If there are no inputs it draws a
%   and displays a blank gamboard. If there are displaysfunction will draw
%   an X or O on the game board and update the logic matrix to match it.
if nargin == 0% checks to see if the function is being called without any inputs
    object = gca;% creates the plot object
    object.XLim = ([0,3]);% limits the plot to 3 wide
    object.YLim = ([0,3]);% limits the plot to 3 high
    hold on
    object = line([1,1],[0,3]);% creates grid lines
    object.Color = [0,0,0];% changes the color to black
