Hi Everyone,
I want to insert new formula (y=y0+A.e(kt))for exponential fittings. I tried it but I could not do it as it was asking for values and I was not sure about the values and options.
Please let me know how can I insert and use this formula for fittings.
Thank you,
Manish

Hi Manish,

If I do not misunderstand your question, you want to define a new function and use it to fit dataset, right? However, I am not sure there is any wrong when create the new function.

Please refer to this tutorial for
http://www.originlab.com/doc/Tutorials/UserDef-FitFunc

To know more detail about “Fitting Function Builder”, please take a look at this help page:

Thanks
