make a graphical board for a tictactoe game in matlab

To make a graphical board for a Tic Tac Toe game in Matlab, you can use the figure and axes functions to create a window and axes object. Then you can use rectangle function to draw the individual squares of the board.

Here is an example code:

main.m
% Create a window and an axes object
figure('Name', 'Tic Tac Toe Board');
ax = axes('Position', [0 0 1 1]);

% Draw board
for i = 1:3
    for j = 1:3
        rectangle(ax, 'Position', [(i-1)/3, (j-1)/3, 1/3, 1/3], 'LineWidth', 2);
    end
end

% Adjust axis properties
axis off;
axis equal;

This code creates a window with a name "Tic Tac Toe Board" and an axes object that fills the entire window. Then, it uses the rectangle function in a loop to draw 9 individual squares of equal size. Finally, the axis off command removes the x and y axis labels and ticks, and the axis equal command makes sure that the aspect ratio of the axes is set to 1:1 so that the squares are squares.
