FIXPDF

 
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 method based on the solution of an
ordinary differential equation. The user must provide subroutines for function
and derivative evaluation. The Jacobian matrix is assumed to be dense. (Note:
This subroutine is generally more robust than the similar routines FIXPNF and
FIXPQF but may be slower by a factor of two.).
 
Classes  :  F2 . Solution of a system of nonlinear equations
 
Type     : Fortran subroutine in HOMPACK package.
Access   : Some uses prohibited. Portable.
