Origin Version (Select Help-->About Origin):
Operating System:windows
origin 6.1
I need to fit a complex function, is it possible with this version,
I have the real part and imaginary part in two columns, I plotted on the same graph window, everything seems fine, and i want to fit for example the imaginary part of the plot with the function i want to use, is it possible? |

Hello burqkbegen,
If you want to fit imaginary part only, viz, you are dealing with real and imaginary parts independently, you can just
1. Highlight Imaginary column.
2. Analysis -> Nonlinear Curve Fit -> Advanced Fitting Tool.
The advanced fitter has the ability to define your own favorite fitting function. More detailed help can be found in menu: Help -> Origin -> Analysis: Curve Fitting
