I´m a new user of origin and I´m trying to find a way to obtain the solution to this problem:
I have three equations with unknown parameters that are related one with each other, and their data tables. I need to fit each curve simultaneously to obtain the best parameters for the 3 curves.
Can I do that with origin?

Hi lalipna:
You can fit multiple datasets to the same function with or without sharing parameters. If you opt NOT to share parameters, you will obtain a different set of parameter values for each dataset. By sharing parameters, you will obtain a single set of parameter values for all datasets.
For more information go to your Origin Help file, select the Index tab and search on "Nonlinear least squares fitter:fitting multiple datasets."
This should get you going.
