NAME

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

CONTENTS

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 :
o <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.

o <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.

o <gsl_ntuple_write($ntuple)>

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

o <gsl_ntuple_bookdata($ntuple)>

This function is a synonym for gsl_ntuple_write.

o <gsl_ntuple_read($ntuple)>

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

o <gsl_ntuple_project()>
o <gsl_ntuple_close($ntuple)>

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

For more informations on the functions, we refer you to the GSL offcial documentation: <http://www.gnu.org/software/gsl/manual/html_node/>
