FORTRAN 77 NEQNF IMSL Solver, 2 variables, 6 equations.

Hello!

I am trying to use NEQNF to solve a system of 6 non linear equations. I need to determine 2 variables to solve my system. According to description i need to define "N" which is the length of "X"(variables) AND "F"(equations).

Does this mean that i can use this solver only if X=F? Because N is defindes as an integer in the example given below in the description.

Or can i define N as a vector? How does declaration of N supposed to look like in this case?

And i have some general questions about the solver:

What happens if there is more than one solution for my system?

I can define XGUESS. Will this guess only be taken for the first step?

Fortran 77, Visual Studio 2008 Pro

Thanks in advance,

ikkebins!
