Comparing a matrix (list[][]) ?

[jairodsl]

Ok, the main idea is compare each element with others elements, and go
saving the minus element positive and his position (X,Y) in the matrix,
of course min function dont let me save this position (X,Y). I dont
know if its possible do that with min function.
