Analysis.IsPositiveUnateFunctionTo

[bool result]=Analysis.IsPositiveUnateFunctionTo(LogicFunction f, var() x);

f : a logic function
x : the index of the variable
result : true | false

Check whether $f$ is positive unate function to its variable x.

The unateness indicates the effect of its logic variables with a logic function when they change their value between (0,1).
