How to create a grid for memory tile game?

How to create a grid for memory tile game in MATLAB. The grid should contain random number of rows and number of columns by the choice of the player.

The grid generation is easy:

nrows = 5;                  % User Input: Number Of Rows
ncols = 7;                  % User Input: NumberOf Columns

XL = [0 nrows];
YL = [0 ncols];

rowx = repmat([0:ncols], 2, 1);
rowy = [min(XL)*ones(1, ncols+1); max(XL)*ones(1, ncols+1)];
colx = [min(YL)*ones(1, nrows+1); max(YL)*ones(1, nrows+1)];
coly = repmat([0:nrows], 2, 1);

figure(1)
plot(rowx, rowy, 'g')
hold on
plot(colx, coly, 'g')
hold off
axis equal tight

Thank You so much!

But how can I display numbers on the tiles so that it displays two similar numbers? Here's my code but it didn't work out with me

A = randi(numRows,numCols);
nums = randperm((numRows*numCols)/2);

Could you please check what's the error with my code?

Thanks

My pleasure!

Using the randi function is definitely the way to go, so that is the correct choice. I took it a bit further. (Note that you have to have the strsplit function to make my code work. If you don’t have it, there is a workaround with a for loop.)

This works:

nrows = 5;                  % User Input: Number Of Rows
ncols = 7;                  % User Input: NumberOf Columns

XL = [0 nrows];
YL = [0 ncols];

rowx = repmat([0:ncols], 2, 1);
rowy = [min(XL)*ones(1, ncols+1); max(XL)*ones(1, ncols+1)];
colx = [min(YL)*ones(1, nrows+1); max(YL)*ones(1, nrows+1)];
coly = repmat([0:nrows], 2, 1);

figure(1)
plot(rowx, rowy, 'g')
hold on
plot(colx, coly, 'g')
hold off
axis equal tight

N = randi(nrows*ncols, 1, nrows*ncols);
Ns = strsplit(sprintf('%2d\n', N));
Ns = Ns(1:end-1);
xmat = repmat([1:ncols], 1, nrows)-0.5;
ymat = repmat([1:nrows], 1, ncols)-0.5;
text(xmat, ymat, Ns, 'HorizontalAlignment','center', 'VerticalAlignment','middle')
