how to add a boarder around a matrix

I'm most likely asking this question wrong but i'm making a simple game

https://www.mathworks.com/matlabcentral/answers/231792-how-do-i-change-one-value-in-a-matrix

and this was my last question but i realized i've made a mistake!

       1     2     3     4     5     6     7     8
       2     0     0     0     0     0     0     0
       3     0     0     0     0     0     0     0
       4     0     0     0     0     0     0     0
       5     0     0     0     0     0     0     0
       6     0     0     0     0     0     0     0
       7     0     0     0     0     0     0     0
       8     0     0     0     0     0     0     0

this is how the board will look like but i want the board to look like this

- 1 2 3 4 5 6 7 8 
1 . . . . . . . . 
2 . . . . . . . . 
3 . . . . . . . . 
4 . . . . . . . . 
5 . . . . . . . . 
6 . . . . . . . . 
7 . . . . . . . . 
8 . . . . . . . .

The dots would be preferred but i've also accepted that the zeros are just fine haha it doesn't effect the game statement really

but how can one create this boarder and also prevent the user from changing the value so if they input 1 1 it would not change the first number of the first row

also How would i indicate that the whole board is full of numbers now?

Where do you want that? If you want to print it to the command window, use fprintf(). If you want it on a GUI, then use GUIDE and make a static text label, or a uigrid, and put that stuff in there.
