Hello, I need to fit my data with the modulus of a complex function. I tried to use the "Imabs" command but the resulting curve do not with the simulation. I wonder if there is the correct way to define a function of modulus of a complex function. The following is what I have as a defined function, y=Imabs((-1i*a2*v+a1*(1i*g2*x-x^2+w2^2))/(v^2+(-1i*g1*x+x^2-w1^2)*(-1i*g2*x+x^2-w2^2)))+C
Here a1,a2,w1,w2,g1,g2,v,C are fitting parameters.
