Hello,
I need to create a lookup table, with the possibility to do the interpolation and the extrapolation?

I have found some stuff here
http://www.ida.liu.se/~pelab/realsim/li … ables.html                for the lookup tables
http://www.ida.liu.se/~pelab/realsim/li … _Math.html                                                      for the interpolation
https://svn.modelica.org/projects/Model … s/Types.mo                for the extrapolation

but unfortunately they are just  sketches

Can you suggest how can I do it?
Should I start from scratch or there are available some more mature libraries to do that?

thank you so much
bye
