Multidimensional minimization in c++

Multidimensional minimization in c++

[Tom Mortimer-Jones]

Has anyone used the multidimensional minimization routines in gsl within
a c++ class?

I would like to include minimization within a class, acting on data
contained within the class, but the gsl_multimin_function_fdf requires
function (method) addresses which have to be static and static methods
cannot work on the non static data within my class instances. Has anyone
found a way to work around this problem or am I doing something wrong?

Thanks for your time,

Tom.

I don't know if there's any special way to handle this elegantly in
C++ generally but with GSL you can always use the void * params
argument of gsl_multimin_function_fdf to pass the necessary
information (e.g. a pointer to self).
