Hi All,
I want to fit the real part of a complex function to my data.

My dependent /independent variables are all real. This is the function i have.
y=(x-G)/((x-G)^2)-D^2)^0.5;

G and D are the variables which i want to fit.
I defined this function in the "Non linear curve fitting". Is there a command like Re[y] that i can use?

Thank you
Pegor
