NAME

       Math::GSL::NTuple - Functions for creating and manipulating ntuples, sets of values

SYNOPSIS

       This module is partially implemented. Patches Welcome!

           use Math::GSL::NTuple qw /:all/;

DESCRIPTION

       Here is a list of all the functions in this module :

       •   <gsl_ntuple_open($filename, $ntuple_data, $size)>

           This function opens an existing ntuple file $filename for reading and returns a
           pointer to a corresponding ntuple struct. The ntuples in the file must have size
           $size. A pointer to memory for the current ntuple row $ntuple_data, which is an array
           reference, must be supplied -- this is used to copy ntuples in and out of the file.

       •   <gsl_ntuple_create>

           This function creates a new write-only ntuple file $filename for ntuples of size $size
           and returns a pointer to the newly created ntuple struct. Any existing file with the
           same name is truncated to zero length and overwritten. A pointer to memory for the
           current ntuple row $ntuple_data, which is an array reference, must be supplied -- this
           is used to copy ntuples in and out of the file.

       •   <gsl_ntuple_write($ntuple)>

           This function writes the current $ntuple $ntuple->{ntuple_data} of size
           $ntuple->{size} to the corresponding file.

       •   <gsl_ntuple_bookdata($ntuple)>

           This function is a synonym for gsl_ntuple_write.

       •   <gsl_ntuple_read($ntuple)>

           This function reads the current row of the ntuple file for ntuple and stores the
           values in $ntuple->{data}.

       •   <gsl_ntuple_project()>

       •   <gsl_ntuple_close($ntuple)>

           This function closes the ntuple file ntuple and frees its associated allocated memory.
