FIXPNS

 
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 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.
 
Usage    : CALL FIXPNS (N, Y, IFLAG, ARCRE, ARCAE, ANSRE, ANSAE, TRACE, A, NFE,
           ARCLEN, YP, YOLD, YPOLD, QR, LENQR, PIVOT, WORK, SSPAR, PAR, IPAR)
