FIXPQF

 
Finds a fixed point or zero of a vector function f(x) or tracks a zero curve of a
general homotopy map rho(a,lambda,x), using an augmented Jacobian algorithm. The
user must provide subroutines for function and derivative evaluation. The
Jacobian matrix is assumed to be dense.
 
Classes  :  F2 . Solution of a system of nonlinear equations
 
Type     : Fortran subroutine in HOMPACK package.
Access   : Some uses prohibited. Portable.
