FIXPDS

 
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 sparse and must be
provided in packed skyline storage format.
 
Classes  :  F2 . Solution of a system of nonlinear equations
 
Type     : Fortran subroutine in HOMPACK package.
Access   : Some uses prohibited. Portable.
Precision: Double.
