I have used the user defind fitting functions, however you are limited to a finite number of characters doing this. All of the examples in the help files and multimedia support are either simple functions, or small functions. The function I require to insert is of the form: const*Summation(S*(S+1)*exp(E(S))/summation(S*exp(E(S)) where the summation is over S and E(S) (a function of S) which are listed in a worksheet separate to the main one (ie the one which we are trying to fit data with). How to tackle this problem is not at all obvious with the helpfiles/instruction manuals/etc. Cheers Richard Original Problem: I am trying to learn how to use origin C to define my functions for use in the NLSF. I cannot find an example of one to use, are there any? The code I want to write is to fit a very large summation which calls information from another sheet within my origin project.
