Minesweeper help with resetting the display screen

How do I create code that will reset the screen back to the original code? Basically I am playing minesweeper and the player (my_position) is set on the top right of the matrix as 100. I need to reset my matrix back to -1s and the 100 at the top.. when my_position steps on a mine (or a 1 in the 'mines' matrix). mines = rand(10) > .85

I had to create a 10x10 matrix of -1s (game_window(1:10,1:10) = -1) . So when my_position on the mines field in correlation to the game_window steps on a (1) in mines I need to reset the screen to 10x10 of -1s and 100 at the top.

Any help?

clf() or cla()

Anything beyond that would require knowledge of how you are drawing onto the screen at present.
