Posted - 12/08/2020 : 03:20:58 AM I am using origin for non linear curve fitting for CO2 breakthrough data. My equation includes the ERFC function. Whenever I tried it says "cannot converge, reason unknown". Please help me if you know how to do it in origin. Thanks in advance |

If the function definition is correct, you may need to tune the initial values of parameters. Other reasons could be: https://www.originlab.com/doc/Origin-Help/The_Reason_Why_Fail_to_Converge
If you would like us to check, please send your data and fitting function to <tech@originlab.com>, also please provide your serial number. Thank you.
