make a board for tictactoe in matlab

To make a board for tictactoe in MATLAB, you can create a window using the figure function and then make a grid using the rectangle function. You can use the line function to draw horizontal and vertical lines to separate the grid into 9 equal squares. Here's an example code:

main.m
% Creating a figure
board = figure('Color',[1 1 1]);
axis equal; axis off; hold on;

% Making the grid
rectangle('Position',[0,0,3,3],'LineWidth',2);
line([1,1],[0,3],'LineWidth',2);
line([2,2],[0,3],'LineWidth',2);
line([0,3],[1,1],'LineWidth',2);
line([0,3],[2,2],'LineWidth',2);
282 chars
11 lines

This will create a simple tictactoe board with 9 squares that can be filled with X's and O's. You can customize the board color and line width as per your preferences.
