Hi,
i use the impulse analyzer to fit a Bremsstrahlung spectra. I've created therefore a FDF-File with a rather complicated fit function. Is it possible to use external data e.g. from the worksheet in the fitfunction during the fit?
That means for a certain "x" (channel) i'll calculate an integer number with one of the fitparameters "x*k=c", read out from the worksheet Column(..), Row(c) a double value and use it in the fit function as factor for my fit function.
e.g.:
int c;
c=k*x;
Fitfunction: y=y0 + x*k*(column,row:c)
I hope it's not too confusing!
Best Regards

Hi Marco:
Here is an example. You don't need to care about the convolution part. The example shows that, inside the function body, you can use Worksheet wks = Project.ActiveLayer(); to get the active worksheet, and then define datasets for worksheet columns. Hope this helps.
Thanks
