Does anyone know of a gradient optimization routine which would minimize
f(x) where x and f are both complex valued vectors. f is non-linear.

All the routines I know of seem to be written for real valued functions.

Any help in this regard would be highly appreciated. Even a list of
references for implementation would be helpful.

I am sorry if this is a trivial question.

Sincerely,
Sarath.

I forgot to mention - I am trying to minimize the l2 norm of f(x).
