There is an error, so please correct it and rewrite the code

error occured in below line

image_matrix = reshape(image_matrix, [block_size, block_size, num_rows, num_cols]);

An error occurred during the following : reshape Size argument must be a real integer

An error occurred during the following : reshape Size argument must be a real integer

An error occurred during the following : reshape Size argument must be a real integer

How should I fix this part?

Or teach me a new code to make a puzzle using Matlab!!!

% Read in the image file

image = imread('picture4.jpg');

% Divide the image into lines based on difficulty level (2x2, 4x4, or 6x6)

difficulty = 4; % Set the difficulty level (4x4 in this example)

[rows, cols, channels] = size(image);

num_rows = difficulty;

num_cols = difficulty;

block_size = rows / num_rows;

% Convert the image to a matrix and reshape it into the appropriate number of rows and columns

image_matrix = im2double(image);

image_matrix = reshape(image_matrix, [block_size, block_size, num_rows, num_cols]); ???????????????

% Shuffle the image

permutation = randperm(num_rows * num_cols);

image_matrix = image_matrix(:,:,permutation);

% Loop until the puzzle is solved

while true

% Display the current state of the puzzle

imshow(image_matrix);

% Prompt the user for their next move

row = input('Enter the row of the tile you want to move: ');

col = input('Enter the column of the tile you want to move: ');

% Check if the move is valid

if row < 1 || row > num_rows || col < 1 || col > num_cols

% Output a buzz sound and display a message if the move is not valid

sound(sin(1:1000),1000); % Output a buzz sound

disp('Invalid move. Please try again.');

else

% Swap the selected tile with the empty space if the move is valid

empty_row = find(all(all(image_matrix == 0, 1), 2), 1); % Find the row with the empty space

empty_col = find(all(all(image_matrix == 0, 2), 3), 1); % Find the column with the empty space

image_matrix(:,:,empty_row,empty_col) = image_matrix(:,:,row,col); % Swap the selected tile with the empty space

image_matrix(:,:,row,col) = 0; % Set the original position of the selected tile to be empty

end

% Check if the puzzle is solved

if isequal(image_matrix, reshape(image, [block_size, block_size, num_rows, num_cols]))

% Display the original image and exit the loop if the puzzle is solved
