Hello,
I use Origin 7G and Windows XP.
I tried to fit some complex data and suddenly the number of Iterations was increased to some strange value. Afterwards I was not able to fit any curve with a self-defined function.
Not even y = ax+b was possible.
I always get "Error 28037. Likely caused by errors in user defined formula or poor parameter initialization"
It's definetly not a problem of the function since easy functions don't work as well and it is not a problem that the starting values are too far off. I take the same functions as before the problem and it does not work.
Thanks for your help
Christian

Hi,
Please check whether you have saved the function in Expression form, whereas you defined it in script Form.
You can delete the "y=" from the definition and re-save, otherwise change the Form to Y-Script and re-save.
