Origin Ver. and Service Release (Select Help-->About Origin): 2023
Operating System: Win10

Hello, is it possible to build a python code from a user defined nonlinear labtalk expression with all the parameters e.g. constraints? I am asking this because I am not able re-produce the perfect fit quality and values I obtained in OriginLab compared to both python and MATLAB.

Best

There is no way to generate Python code for the LabTalk function. The discrepancy of the fitting result could be due to other reasons, such as the fitting converging to a local minimum.
