  77 Math::GSL::Sort - Functions for sorting data
  78
  79 =head1 SYNOPSIS
  80
  81     use Math::GSL::Sort qw/:all/;
  82     my $x      = [ 2**15, 1.67, 20e5,
  83                     -17, 6900, 1/3 , 42e-10 ];
  84     my $sorted = gsl_sort($x, 1, $#$x+1 );

  86
  87 =head1 DESCRIPTION
  88
  89 Here is a list of all the functions included in this module :
  90
  91 =over
  92
  93 =item * gsl_sort_vector($v) - This function sorts the elements of the vector $v into ascending numerical order.
  94
  95 =item * gsl_sort_vector_index($p, $v) - This function indirectly sorts the elements of the vector $v into ascending order, storing the resulting permutation in $p. The elements of $p give the index of the vector element which would have been stored in that position if the vector had been sorted in place. The first element of $p gives the index of the least element in $v, and the last element of $p gives the index of the greatest element in $v. The vector $v is not changed.
  96
  97 =item * gsl_sort_vector_smallest
  98
  99 =item * gsl_sort_vector_smallest_index
 100
 101 =item * gsl_sort_vector_largest
 102
 103 =item * gsl_sort_vector_largest_index
 104
 105 =item * gsl_sort($data, $stride, $n) - This function returns an array reference to the sorted $n elements of the array $data with stride $stride into ascending numerical order.
 106
 107 =item * gsl_sort_index
 108
 109 =item * gsl_sort_smallest
 110
 111 =item * gsl_sort_smallest_index
 112
 113 =item * gsl_sort_largest
 114
 115 =item * gsl_sort_largest_index
 116
 117 =back
 118
 119  You have to add the functions you want to use inside the qw /put_funtion_here /.
 120  You can also write use Math::GSL::Sort qw/:all/ to use all avaible functions of the module.
 121  Other tags are also avaible, here is a complete list of all tags for this module :
 122
 123 =over
 124
 125 =item all
 126
 127 =item plain
 128
 129 =item vector
 130
 131 =back
 132
 133 For more informations on the functions, we refer you to the GSL offcial documentation:
