Origin Version (Select Help-->About Origin): 7 SR1
Operating System:XP pro
I'm trying to fit 4 datasets using a function from an external dll. The fit has 5 parameters, 4 of which are shared. 2 of the shared parameters are allowed to vary and all other parameters, including the non-shared ones, are fixed. The non-shared parameter value is different for each dataset.
Interfacing to the dll function works and there is no problem when fitting or generating a single curve, however when fitting multiple datasets it generates 4 identical curves using only the first 'version' of the non-shared parameter.
any help or suggestions much appreciated.
Cheers. |

Hi aidan23,
Difficult to say what is going on without trying with your function and your data.
Best to send your FDF, your DLL and data, (along with exact procedure you followed and what values you assigned for parameters etc) to tech support so they can take a look.
