I have data in 2 columns: col(V) = (x-axis) col(F_L) = (y-axis)
I would like to fit my data with the equation in the attached image.
I tried to create my own fitting function (Going to tools>Fitting Function Builder) however, the problem is that to create a function, the function body has to have only the dependent variable y (in my case F_L) on the left-hand side of "=". I will be glad to hear your comments on how I can create this fitting function.
Soma more info: Independent variable: V Dependent variable: F_L parameters: F_0 and B Constants: F_* and K_B and K_series and T |

I suggest you can try to define an implicit function.
Please refer to this help pages and video tutorial: http://www.originlab.com/doc/Quick-Help/Implicit-Function http://www.originlab.com/doc/Origin-Help/Fitting-Implicit http://originlab.com/doc/Tutorials/ImplicitFit-3Var http://www.originlab.com/doc/Origin-Help/Fitting-Implicit
Also, I suggest you can change the variable, parameters and constants to a simple characters. Because I do not confirm " F_*" this kind expression of the Constants could be used in the Fitting Function.
Thanks Jacqueline OriginLab |
