Hi,

I have to fit data with a quite complex model, where the fit value is a quotient of two two-dimensional integrals. Is it possible to define such fitting procedure in origin?

I tried the following:

http://www.originlab.com/doc/Tutorials/Fitting-Integral-NAG
http://www.originlab.com/doc/Tutorials/Fitting-Integral-LabTalk

but they seem to be limited to one one-dimensional integral.

I would be very grateful for any help.

I am using Origin 2015.

Hi,

For two-dimensional integrals, I would suggest you use the nag function, d01fcc or d01gbc. You can look at their document as below

Then you can define your fitting function with the nag functions above accordingly to tutorial below
