Problem 1961. Finding neighbors of [-1:1] in a matrix....
Hello All!
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!

Good problem. You should generalise it with more tests (size of the matrix, different gap...).
I suspect that my solution isn't correct.
