NAME

       PDL::GSL::MROOT - PDL interface to multidimensional root-finding routines in GSL

DESCRIPTION

       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.

SYNOPSIS

          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;
         }

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.
