[Help-gsl] Multidimensional Minimization of a nonlinear function.

[Eric Germaneau]

Hi,

I'd like to perform the minimisation of a 6-D nonlinear function. By 
nonlinear I want to say tha there is no analytic expression of this 
function.
I've read that the simplex algorithm is very efficient for such task.
Id like to use gsl to solve this problem but it seems that with the 
'gsl_multimin.h'  library one have to provide the espression of the 
function one wish to minimize.
So does someone has an idea for solving this problem with gsl?
If it's not possible what can i do?
Thanks in advance,
regards,

                             Eric.
