Non linear multiD systems: examples


I am looking for a multidimensional example (dim > 2, for dim=2 it exists) of how
to properly use GSLMultiRootFinder to solve a non linear system.
Can I find it somewhere?
A corollary question is if one of the implemented methods is known to work
better with a higher number of dimensions.

Thank you

There is an example here: … ot_8C.html


as I said, I need an example for N>2.
I know that one existed, but am not sure I know how to extend it properly.

Also, there is the question about tests on multiD systems…

Thank you again
