Hi, I'm having problems with the FindMinimum. I'm currently getting errors like this: FindMinimum::nrlnum: The function value {0.335521+43899.8 \ [ImaginaryI],0.376043+43899.8 \[ImaginaryI],0.424669+43899.8 \ [ImaginaryI],<<6>>,0.311208+46311.9 \[ImaginaryI],<<27>>} is not a list of real numbers with dimensions {37} at {x0,y0,x1,y1,hh0,hh1} = {0.00580647,-2.13969*10^20,-9.86301*10^-6,1.23875*10^20,-30574.3,19.6042}. I guess this happens because the function I'm trying to fit with experimantal data, gets imaginary values for some values of the parameters. How can I avoid this and get meaningful results ? Thanks Teodoro
