The latest version of this package is HOMPACK90, in netlib at TOMS 777.
HOMPACK is an older suite of FORTRAN 77 subroutines for solving nonlinear systems of equations by homotopy methods. There are subroutines for fixed point, zero finding, and general homotopy curve tracking problems, utilizing both dense and sparse Jacobian matrices, and implementing three different algorithms: ODE-based, normal flow, and augmented Jacobian.
