FIXPNF

 
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 a normal flow 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.
Precision: Double.
