 126 Math::GSL::Sort - Functions for sorting data
 127
 128 =head1 SYNOPSIS
 129
 130     use Math::GSL::Sort qw/:all/;
 131     my $x      = [ 2**15, 1.67, 20e5,
 132                     -17, 6900, 1/3 , 42e-10 ];
 133     my $sorted = gsl_sort($x, 1, $#$x+1 );
 134
 135
 136 =head1 DESCRIPTION
 137
 138 Here is a list of all the functions included in this module :
 139
 140 =over
 141
 142 =item * gsl_sort_vector($v) - This function sorts the elements of the vector $v into ascending numerical order.
 143
 144 =item * gsl_sort_vector_index($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 $v is not changed.
 145
 146 =item * gsl_sort_vector_smallest
 147
 148 =item * gsl_sort_vector_smallest_index
 149
 150 =item * gsl_sort_vector_largest
 151
 152 =item * gsl_sort_vector_largest_index
 153
 154 =item * gsl_sort($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.
 155
 156 =item * gsl_sort_index
 157
 158 =item * gsl_sort_smallest
 159
 160 =item * gsl_sort_smallest_index
 161
 162 =item * gsl_sort_largest
 163
 164 =item * gsl_sort_largest_index
 165
 166 =back
 167
 168  You have to add the functions you want to use inside the qw /put_funtion_here /.
 169  You can also write use Math::GSL::Sort qw/:all/ to use all avaible functions of the module.
 170  Other tags are also avaible, here is a complete list of all tags for this module :
 171
 172 =over
 173
 174 =item all
 175
 176 =item plain
 177
 178 =item vector
 179
 180 =back
 181
