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} =
I guess this happens because the function I'm trying to fit with
experimantal data, gets imaginary values for some values of the
How can I avoid this and get meaningful results ?
