What should i do in order to edit the nonlinear formula that contained in the Originlab library. For example, I want to edit Hill formula to langmuir formula. Both of this formula have the similarities in numerator side but different in denominator side. Thank you for your attention

Hi:
The circular is an implicit function? If so, we haven't support this feature in current version.
Thanks

Hi:
I think better to create a new user-defined fitting function. This tutorial may help.
Thanks

Hi shirley,
first of all, thanks for replying my message. But I meet the new prob. Every time I try to fit this equation I get a message stating my fitting function is not completed. The function that I already edit is:
y=Vmax*x*k/(1+x*k)
The parameters I have a values are x,y and Vmax. The value of k need to be determined from the curve fit.
Thank you again.

Hi Nadhra,
To edit a built-in function, you can duplicate it and then edit it in the Fitting Function Organizer.
Besides, you can quote a built-in function to define a user-defined function.
