Well I found this one fun to figure out, all you have to do is make a matrix of 1's or 0's (true or false) that show whether or not a number in a matrix is sitting directly next to (a neighbor) that is number that is +1 or -1 or == to that of the original number. Here are some examples:

M1 = [1 2 1; 5 6 7; 2 3 6]

SO now find numbers next to one another that are +1 of each-other.

output = [1 1 1; 1 1 1; 1 1 1] One more:

M2 = [8 8 8; 4 4 4; 1 9 7]

SO now find numbers next to one another that are +1 of each-other.

output = [1 1 1; 1 1 1; 0 0 0]

One more:

M3 = [1 8 5; 4 10 22; 1 66 7]

SO now find numbers next to one another that are +1 of each-other.

output = [0 0 0; 0 0 0; 0 0 0]

Well good luck!
