lookup table for a function

Hey guys I'm trying to use a lookup table for a function that is not monotonically increasing, but simulink is saying to me that the points of this function should be monotonically increasing. How do I do this:

Use multiple tables where each complies with the rules -- but how are you going to know which is the correct response when there are two (or more) possible values (which, of course, is why the restriction in the first place)???

Ok. But if my function is monotonically decreasing it gives me the same warning. Actually, for me, only the decreasing part of the function is enough.

[dpb]

I don't know Simulink but that surprises me that decreasing monotonically is an issue. Are you sure it is monotonic or does it have a repeated value, maybe?

Mayhaps need to see the data to comment further...

I've already solved it!

if you have decimal numbers in your data entries make sure that you didn't use ',' instead of '.' in the decimal number
