HYBRD1

 
Finds a zero of a system of n nonlinear functions in n variables by a modification of
the Powell hybrid method. The user must provide a subroutine which calculates the
functions. The Jacobian is then calculated by a forward-difference
approximation. Easy-to-user driver for MINPACK routine HYBRD.
 
Classes  :  F2 . Solution of a system of nonlinear equations
 
Type     : Fortran subroutine in MINPACK package.
Access   : Public domain. Portable.
Precision: Double.
Note     : Single precision version available in NETLIB package SMINPACK.
 
Usage    : CALL HYBRD1(FCN, N, X, FVEC, TOL, INFO, WA, LWA)
 
Details  : Fullsource Source
