Greetings, Here is the situation: I have four notebooks. In each I have datasets and I use Interpolation[dataset] to get an interpolation function for each dataset. Now I need to use those four interpolations in a fifth notebook that is not, probably, going to run at the same time as the other (they will be closed). I do not want to read all the data again and compute the interpolations to use them. So, is it possible to save or copy the different interpolations to a new notebook and use them? I could probably use FindFit and then copy the polynomial function in a different notebook to use it. But I need a good fit, a very good fit. Actually I need the precision given by Interpolation. Any suggestions? Thanks, Robert Robert Pigeon
