帮我写一个2048游戏能在MATLAB里运行的代码

好的，这是一个简单的2048游戏MATLAB代码：

function play_2048()
% 2048 game
% by Aneesh Komanduri

% Initialize game
board = zeros(4,4);
board = add_tile(board);
board = add_tile(board);
disp_board(board)

% Play game until game over
while ~game_over(board)
    % Get user input
    direction = input('Enter direction: ','s');
    switch direction
        case 'w'
            board = move_up(board);
        case 'a'
            board = move_left(board);
        case 's'
            board = move_down(board);
        case 'd'
            board = move_right(board);
        otherwise
            disp('Invalid direction!')
    end
    
    % Add new tile and display board
    board = add_tile(board);
    disp_board(board)
end

% Game over message
disp('Game over!')

end

function disp_board(board)
% Display board
disp('----------------')
for i = 1:size(board,1)
    fprintf('|')
    for j = 1:size(board,2)
        if board(i,j) == 0
            fprintf('    ')
        else
            fprintf('%4d',board(i,j))
        end
        fprintf('|')
    end
    fprintf('\n----------------\n')
end
end

function board = add_tile(board)
% Add new tile to board (either 2 or 4)
if rand < 0.9
    tile_value = 2;
else
    tile_value = 4;
end
[i,j] = find(board == 0);
random_index = randi(length(i));
board(i(random_index),j(random_index)) = tile_value;
end

function board = move_up(board)
% Move tiles up
for j = 1:size(board,2)
    column = board(:,j);
    nonzeros = column(column ~= 0);
    zeros = length(column) - length(nonzeros);
    column = [nonzeros; zeros*0];
    for i = 1:length(column)-1
        if column(i) == column(i+1) && column(i) ~= 0
            column(i) = 2*column(i);
            column(i+1) = 0;
        end
    end
    nonzeros = column(column ~= 0);
    zeros = length(column) - length(nonzeros);
    column = [nonzeros; zeros*0];
    board(:,j) = column;
end
end

function board = move_down(board)
% Move tiles down
for j = 1:size(board,2)
    column = board(:,j);
    nonzeros = column(column ~= 0);
    zeros = length(column) - length(nonzeros);
    column = [zeros*0; nonzeros];
    for i = length(column):-1:2
        if column(i) == column(i-1) && column(i) ~= 0
            column(i) = 2*column(i);
            column(i-1) = 0;
        end
    end
    nonzeros = column(column ~= 0);
    zeros = length(column) - length(nonzeros);
    column = [zeros*0; nonzeros];
    board(:,j) = column;
end
end

function board = move_left(board)
% Move tiles left
for i = 1:size(board,1)
    row = board(i,:);
    nonzeros = row(row ~= 0);
    zeros = length(row) - length(nonzeros);
    row = [nonzeros, zeros*0];
    for j = 1:length(row)-1
        if row(j) == row(j+1) && row(j) ~= 0
            row(j) = 2*row(j);
            row(j+1) = 0;
        end
    end
    nonzeros = row(row ~= 0);
    zeros = length(row) - length(nonzeros);
    row = [nonzeros, zeros*0];
    board(i,:) = row;
end
end

function board = move_right(board)
% Move tiles right
for i = 1:size(board,1)
    row = board(i,:);
    nonzeros = row(row ~= 0);
    zeros = length(row) - length(nonzeros);
    row = [zeros*0, nonzeros];
    for j = length(row):-1:2
        if row(j) == row(j-1) && row(j) ~= 0
            row(j) = 2*row(j);
            row(j-1) = 0;
        end
    end
    nonzeros = row(row ~= 0);
    zeros = length(row) - length(nonzeros);
    row = [zeros*0, nonzeros];
    board(i,:) = row;
end
end

function game_over_flag = game_over(board)
% Check if game is over
game_over_flag = true;
for i = 1:size(board,1)
    for j = 1:size(board,2)
        if board(i,j) == 0
            game_over_flag = false;
            return
        end
        if i > 1 && board(i,j) == board(i-1,j)
            game_over_flag = false;
            return
        end
        if i < size(board,1) && board(i,j) == board(i+1,j)
            game_over_flag = false;
            return
        end
        if j > 1 && board(i,j) == board(i,j-1)
            game_over_flag = false;
            return
        end
        if j < size(board,2) && board(i,j) == board(i,j+1)
            game_over_flag = false;
            return
        end
    end
end
end

运行这个函数，你就可以玩2048游戏了！
