How could I solve this?

Best Answer

funvtion Out = findeven(In)
Out = ~mod(In,2)
end
Assuming:
In =
      -6    -5    -2     0
       1     2     3     4
       5     6     7     8
       9    10    11    12
Out =
       1     0     1     1
       0     1     0     1
       0     1     0     1
       0     1     0     1
