Using complex numbers in Fletcher Reeves optimization method

[Dze]

Hello,

I would like to minimize a function of 4 complex variables with the Fletcher Reeves optimization method (Conjugate Gradient VI).
Is it possible to do it with this VI or with HiQ4.5 ?

(for S-parameters specialists) The purpose is to de-embed using optimization method.

Thanks,

Dze

I believe that the "Conjugate Gradient nD.vi" and the optimize function in HiQ only work with real vectors. Most of the solve functions in HiQ work with complex numbers, and you may be able to create your own algorithm for the purpose, but I don't think that there is already a function that will do quite what you want.
