Hi,

I have an automatically generated equation system that should be solved
in a predefined sequence (which will work).

The problem is:
Some equations can be solved by NSolve[], others only by FindRoot[].
Unfortunately I have to decide which method is to be used before the
equation system is handed over to Mathematica.  So, is there any way to
launch a "solve"-kind of operation that automatically chooses the method
applicable to the specific equation it should solve?

Thanks in advance for help,
Jörg
