Hi Mike,

The error occures during execution.
The error msg is: Error 28037.Likely caused by errors in the user defined formula or poor parameter initialization.

this is the code im using:

using NLSF = LabTalk.NLSF;
NLSF.Init();
NLSF.Func$ = "user6";
NLSF.P4 = 2.50175;
NLSF.FitData$ = crvData.GetName();
NLSF.Execute("parainit");
NLSF.Wtype = 1;
NLSF.W$ = dsErr.GetName();
NLSF.ChiSqrErr = 0;
NLSF.Fit(100);
NLSF.Fit(100);
NLSF.Fit(100);
NLSF.PasteParams("P");
NLSF.End();
}


and this is the user6 function:
y=P1*(1+P2*cos(2*Pi*(x-P3)/P4))

i want to fix P4 to the value 2.50175

Thanks in advance
Best regards,
Pegor

Hi Pegor,

Please use the "Reply to Topic" button to keep your posts in one thread. It gets confusing when you scatter the same thread over separate topics.

I suspect that user6 is a function defined by you and that you haven't provided a parameter initialization script. In that case NLSF.Execute("parainit") does nothing and you must initialize all parameters in your Origin C function...

using NLSF = LabTalk.NLSF;
NLSF.Init();
NLSF.Func$ = "user6";
NLSF.P1 = 1.234; // use an appropriate value
NLSF.P2 = 5.678; // ditto
NLSF.P3 = 9.10; // ditto
NLSF.P4 = 2.50175;
NLSF.V4 = 0; // fix parameter 4
NLSF.FitData$ = crvData.GetName();
//NLSF.Execute("parainit");
NLSF.Wtype = 1;
NLSF.W$ = dsErr.GetName();
NLSF.ChiSqrErr = 0;
NLSF.Fit(100);
NLSF.Fit(100);
NLSF.Fit(100);
NLSF.PasteParams("P");
NLSF.End();
