Hello,
I want to fit a data to these non-linear kinetic models : Lagergren's pseudo-first order and Ho's pseudo-second order.
This what i found on the website of OriginLab but it didn't work for me.
Need for your help please.
Thank you |

Hi,
If you do not want to fit through apparent fit using linear fit tool, you can fit with our nonlinear fitting tool.
If the function form is explicit where the y can be separated from x, then you can define a fitting function on your own and use it to fit. A sample tutorial is shown below:
http://www.originlab.com/doc/Tutorials/UserDef-FitFunc
If the function you want to fit cannot be separated, you can fit using our implicit fitting by defining an implicit fitting function:
