user-defined curve fitting
thuzhengc12
Hi,
I would like to fit my data using a specific function y=a*x/(b+x). It seems that this can only be done by programming instead of GUI, could anyone kindly provide a template or direct instruction for doing user-defined curve fitting? Thank you very much for your help!
Best,
Chu
Look in the curve fitting dialog: Analysis > Curve Fitting, for the 'New Fit Function' button.
a and b are the fit coefficients, x is the independent variable.
Click the 'Help' button (or execute DisplayHelpTopic "curve fitting") for instructions on how to set up a user defined function.
If you run into problems, ask here.

Check out the menu: Analysis --> Curve Fitting, then the "New Fit Function" button on the "Function and Data" tab.

Hi Tony, I was a bit too late ... I think not the first time ;-)
