I have a matlab code that creates a puzzle to where the user can move/slide the pieces by using the arrow keys, how can I turn this into an app?

My code is VERY long and also contains two functions. Basically it is a little game that takes an image, scrambles the image and allows the user to use the left, right, up, down keys on the computer keyboard to move the pieces. How can I take this working code and transform it into an app using the matlab app design. I need to put this in a working Matlab GUI app. Please assist.

1st function:

function s = puzzlefunc
done = 0;
while done == 0
    m = reshape([randperm(8) 9],3,3);
    ind = find(m==8);
    ind1 = find(m==7);
    s=m;
    if abs(ind-ind1)<6 && abs(ind-ind1)>3
        done = 1;
    end
end

2nd function:

function w = additionpuzz(w,ind1,ind2)
temp = w(ind1);
w(ind1) = w(ind2);
w(ind2) = temp;

main script: (this is what creates the puzzle game)

clc;clear;close all;warning off;
image = imread('puzzleIMAGE.jpg');
image1 = imresize(image,[600 600]);
imshow(image1);

What is the difference between this question and your existing https://www.mathworks.com/matlabcentral/answers/1689335-turning-a-moving-piece-puzzle-on-a-matlab-script-into-an-app-component?s_tid=srchtitle ?

[Olivia Garza]

@Walter Roberson The other question I did not include my main script and I was trying to input the functions into the app design. I am trying to incorporate everything in to the app design to create a game within the app using the functions and main script.

[Walter Roberson]

If you are doing this all in app designer, then define each function as a method . The ones that do not need app as an input (in order to get at properties you have defined), then define those as static methods; the ones that do need app, have app be the first parameter.
