Create matlab code for memory game.

I want to create matlab code for following memory game.

Request input from the player to select two cards by entering row and column numbers.

Decision: Are the two selected/newly discovered letters the same?

clear
clc
disp('Welcome to the Memory Game Buddy!')
disp('Here is the board so far, buddy!!!')

% initialize the board
 board = cell(4,8);


% prompt user
prompt = "Please enter first card (row col):";
x = input(prompt);

prompt2 = "Please enter second card (row col):";
y = input(prompt2);

You should be checking

isnumeric(x) && isnumeric(y) && numel(x) == 2 && numel(y) == 2

and you should also be checking that any(x ~= y) or else you would be permitting the user to select the same location twice, and of course the values would be the same in that case...

Thank you. Firstly, I need to change all the values in the cell to display '+' as this signifies an unturned card. How could I do this?

Secondly, how do I go about randomly allocating 32 cards consisting of the letters A-H appearing four times. Any pairing of the same letters should be considered a successful find.

clear
clc
disp('Welcome to the Memory Game Buddy!')
disp('Here is the board so far, buddy!!!')

% initialize the board
 cell(4,8);
 cell{1,8} = '+';

% prompt user
prompt = "Please enter first card (row col):";
x = input(prompt);

prompt2 = "Please enter second card (row col):";
y = input(prompt2);

isnumeric(x) && isnumeric(y) && numel(x) == 2 && numel(y) == 2

any(x ~= y)

% Decision: Are the two selected/newly discovered letters the same? 
% If the same, congratulate the player and keep the cards face-up (keep displaying the letters) 
% If not the same, display board with the letters, then remove them after a key press 


% Decision: Has the entire game board been discovered yet? 
% If not, clear the screen after key press and go back to step 2.

 cell(4,8);

That would generate a 4 x 8 cell array, and then throw it away.

 cell{1,8} = '+';

That would generate a 1 x 8 cell array named cell and assign '+' to the last column of the row. After you did this, the name cell would be a variable and it would no longer be possible to explicitly allocate cell arrays.

You should be assigning values to variables

 clear cell
 board = cell(4,8);
 board(:) = {'+'}

board = 4×8 cell array
    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}
    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}
    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}
    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}    {'+'}

Then

 isnumeric(x) && isnumeric(y) && numel(x) == 2 && numel(y) == 2

You are calculating a logical result and displaying it, but you should instead be using it to make a decision with an if statement.

Techniques for filling in the hidden board

gorp = repmat('27=@/',1,3)

gorp = '27=@/27=@/27=@/'

gorp = gorp(randperm(numel(gorp)))

gorp = '/77=/@22/2=7=@@'

gorp = reshape(gorp, 3, 5)

gorp = 3×5 char array
    '/=22='
    '7/2=@'
    '7@/7@'

Thank you for the help. I'm having trouble knowing how to randomly allocate 32 cards consisting of the letters A-H appearing four times within the cell array.

clear
clc
disp('Welcome to the Memory Game Buddy!')
disp('Here is the board so far, buddy!!!')

% initialize the board
clear cell
 board = cell(4,8);
 board(:) = {'+'}

% prompt user
prompt = "Please enter first card (row col):";
x = input(prompt);

prompt2 = "Please enter second card (row col):";
y = input(prompt2);

isnumeric(x) && isnumeric(y) && numel(x) == 2 && numel(y) == 2;

gorp = repmat('27=@/',1,3)

gorp = gorp(randperm(numel(gorp)))

gorp = reshape(gorp, 3, 5)

% Decision: Are the two selected/newly discovered letters the same? 
% If the same, congratulate the player and keep the cards face-up (keep displaying the letters) 
% If not the same, display board with the letters, then remove them after a key press 


% Decision: Has the entire game board been discovered yet? 
% If not, clear the screen after key press and go back to step 2. 

[Walter Roberson]

gorp = repmat('27=@/',1,3)

That takes 5 different characters and repeats each one 3 times

gorp = gorp(randperm(numel(gorp)))

and that scrambles into a random order

gorp = reshape(gorp, 3, 5)

and that turns it into a 3 x 5 array in which each of the 5 characters is repeated 3 times.

You should be able to use the same kinds of techniques to repeat 8 different characters 4 times and create a 4 x 8 array from the results.

isnumeric(x) && isnumeric(y) && numel(x) == 2 && numel(y) == 2;

Well, before you used to be computing the logical result and displaying it instead of using it to make a decision. Now you have progressed to computing the logical result and discarding it, without using it to make a decision.
