I am trying to curve fit a complex function.

I am have been trying to curve fit a complex function. I dnt know whether code I have used is proper or not.

I have attached the codes below.

If your full function is like:

F=(K1/(1+(w/sigma)^2))*0.001+((1j*c1*sigma)/(1+(sigma/w)^2))*0.001;

where F is complex data type

and also the parameters of K1 and c1 are all complex type, then the result will be:

Sum Squared Error (SSE): 330.333035512392
Root of Mean Square Error (RMSE): 3.70996987584576
Correlation Coef. (R): 0.9939271671453
R-Square: 0.987891213589481

Parameter  	Best Estimate    
---------  	-------------    
k1.realpart	36022.5432052983 
k1.imagpart	173011.277144565 
c1.realpart	3.85052366252263 
c1.imagpart	-31.9279234134069

How did you solve this?
