1   Pass
x = [1 2 1; 5 6 7; 2 3 6]; output = [1 1 1; 1 1 1; 1 1 1] assert(isequal(neighbors(x),output))

output = 1 1 1 1 1 1 1 1 1
2   Pass
x = [8 8 8; 4 4 4; 1 9 7] output = [1 1 1; 1 1 1; 0 0 0] assert(isequal(neighbors(x),output))

x = 8 8 8 4 4 4 1 9 7 output = 1 1 1 1 1 1 0 0 0 [Warning: This concatenation operation includes an empty array with an incorrect number of rows. Concatenation including empty arrays will require all arrays to have the same number of rows in a future release.]
3   Pass
x = [1 8 5; 4 10 22; 1 66 7] output = [0 0 0; 0 0 0; 0 0 0] assert(isequal(neighbors(x),output))
