Origin Ver. and Service Release (Select Help-->About Origin): Origin Pro 9
Operating System: Win7 32 bit
Deal all,
I have to fit my data using a function in dll file format.
Can you explain me step by step (for a dummies) how to import dll file in Origin Pro 9?
Here are file:

Hi lsm85,
We have already have a sample shipped with Origin to show you how to create the DLL, import it into Origin and then use it to create the user fitting function.
Please follow the instruction below to install this sample:
http://www.originlab.com/doc/Origin-Help/NLFit-ExternalDLL
Once you installed this opx, there will be a PDF file under the folder <User File Folder>/Fitting with External DLL, which will show you all details about using external dll to create fitting function.
With this PDF, please firstly confirm that you have created the DLL in the right way. And then follow from step 7 in page 3 to learn how to import the DLL in Origin and use it to define fitting function.
Any problem, please feel free to contact us.
Thanks,
Shirley

Here is the script that I should receive after fitting:
Equation: double F = *lpValue;
double SzF2 = S*S/(F*F);
double dRR;
double rhoBar2 = Pu_s_Pr*Pu_s_Pr;
if(F<S)
{
dRR = 2*F/((1+1/rhoBar2)*(3*S));
}else
{
dRR = 1 - SzF2;
dRR+= 2*(pow(S/F,rhoBar2)-SzF2)/(rhoBar2-2);
dRR+= ( (6*pow(S/F,rhoBar2))/(1+1/rhoBar2)-2*SzF2*rhoBar2)/(6-3*rhoBar2);
}
dRR+=koef*F;
dRR*= Lam/4;
