Hey everybody
does anybody know how to fit this function in origin:
Y=(A/(X-2875-iF))^2
where i is a complex number |

Hello Shahir,
For fitting complex function, we use Origin C to build a user defined function in Fitting Function Builder, please refer to this link for details: http://www.originlab.com/doc/Tutorials/Fitting-ComplexFunc
I guess your data is consist of X,F,Y1 and Y2 four columns, so you can also refer to the function body code below which has a similar form with your function.
complex x; //Independent Variables:
x.m_re=x1 ; //real part
x.m_im=x2 ; //image part
complex y; //Dependent Variables:
y= A/(x*x); //complex function
y1 = y.m_re; //real part
y2 = y.m_im; //image part
Best regards,
Jason Zhao
