For those mathematica wizs, please help me.
My question is how to find the max. value of its neighbors in a matrix, i.e.
if you have a matrix
1 2 3
2 3 4
2 1 1
(it'll always be a square matrix)
the max of the neighbors of cell [1,1] would be 3 (cell [2,2]), right?
so new cell [1,1] will be 3. Like that, you'll have a new matrix, in this case,
3 4 4
3 4 4
3 4 4
(including the cell itself, e.g. cell [2,3]) and the boundaries are all 0s.
Now I don't want to use like variable a[i,j], instead I wanna use a={{...},...,{...}}
PLease help me if you would.
Thanks in advance.
