PDL::GSL::MROOT3pm

Pdl interface to multidimensional root-finding routines in gsl

Usage

   use PDL;
   use PDL::GSL::MROOT;
   my $init = pdl (-10.00, -5.0);
   my $epsabs = 1e-7;
  $res = gslmroot_fsolver($init, \&rosenbrock,
                          {Method => 0, EpsAbs => $epsabs});
 
  sub rosenbrock{
     my ($x) = @_;
     my $c = 1;
     my $d = 10;
     my $y = zeroes($x);
     my $y0 = $y->slice(0);
     $y0 .=  $c * (1 - $x->slice(0));
     my $y1 = $y->slice(1);
     $y1 .=  $d * ($x->slice(1) - $x->slice(0)**2);
     return $y;
  }

Overview

This is an interface to the multidimensional root-finding package present in the GNU Scientific Library.

At the moment there is a single function gslmroot_fsolver which provides an interface to the algorithms in the GSL library that do not use derivatives.

Functions

gslmroot_fsolver

  Signature: (double [io]xfree(n);   double epsabs(); int method(); SV* function1)

info not available

gslmroot_fsolver does not process bad values. It will set the bad-value flag of all output ndarrays if the flag is set for any of the input ndarrays.
