Origin Ver.originlab 2019 and Service Release (Select Help-->About Origin):
Operating System: window 10 pro
Hello. Dear friends.
I fitted by origin C in user defined fitting.
In the fit function, additionally, I want to extract real and imaginary value into worksheet coulomb;
Do you know how to do it?
((( Importantly, the fit data is numerically merged of real and imaginary. So the y value cannot separated.)))
----------------------------------------------------------------------
void _nlsMycomplexFitFunction(
// Fit Parameter(s):
double a1, double a2, double a3,
// Independent Variable(s):
double x,
// Dependent Variable(s):
double& y)
{
double real;
double imaginary;
complex result=0;
:
:
real=result.m_re; //<---- this
imaginary=result.m_im; //<-----this
y=real+imaginary;
// End of editable part

Hi,
To fit a complex function, you will need to put real and imaginary values into two columns, and the outputs are also in two columns. Please refer to this tutorial:
