How to add smaller matrix into bigger matrix? (Tetris based idea)

We are creating a Tetris game for fun! & so far have blocks block{1} = [1 1; 1 1]; block{2} = [1 1; 0 1; 0 1]; block{3} = [1 1; 1 0; 1 0]; block{4} = [0 1 1; 1 1 0]; block{5} = [1 1 0; 0 1 1]; block{6} = [1 1 1 1]; block{7} = [0 1 0; 1 1 1];

and they get randomly chosen, but we then need to put the block on our game board

tetris = zeros(18, 10); %Gameboard and dimensions

we've tried a few things and they aren't working yet, any thoughts or input would be awesome! Thanks so much!

You want to add or place the block some where in the tetris?

Yes! We want to place it at the top so that it seems to have just entered the matrix of the game

To add, for example, block 3 with the upper left corner at row i, column j:

b = block{3}; tetris(i:i+size(b,1)-1, j:j+size(b,2)-1) = b;

Thank you so much! You're the best! You're a Matlab genius
