Origin Version (Select Help-->About Origin): 7.5G
Operating System:Win XP

Hi,
I', trying to fit data to the following function

I have a data column q (independent variable) and Sion (dependent variable) I have been looking at the posts about fitting with an integral, but things like those suggested in http://www.originlab.com/www/support/resultstech.aspx?ID=121&language=English&Version=7.5
didn't work. Can anyone help?

Thanks in advance,

Jose

This may give some basical idea for your problem:
> Using the Trapezoid Rule for the approximation to the integral;
> Add a precision for the summation for the infinitive integral.
