multidimensional root finding

["Pawel Suchanecki" <subdcc@.........>]

Hello!

I used following solvers to solve simple kinematics problem defined by
12 equations of 2nd order:

  gsl_multiroot_fsolver_hybrid,
  gsl_multiroot_fsolver_hybrids,
  gsl_multiroot_fdfsolver_gnewton,
  gsl_multiroot_fdfsolver_newton,
  gsl_multiroot_fdfsolver_hybridsj,
  gsl_multiroot_fdfsolver_hybrids,
  gsl_multiroot_fdfsolver_hybridj;

Only the last one produces the acceptable solution.

Can I use any other estimation methods than Rosenbrock's
(rosenbrock_f, rosenbrock_df)?

Where can I find this in source (I grep /usr/include/gsl for
"rosenbrock" on my GNU/Linux system and I can not find it)?

Thank you,

P.
