 239  You have to add the functions you want to use inside the qw /put_funtion_here /.
 240  You can also write use Math::GSL::PowInt qw/:name_of_tag/ to use all avaible functions of the module.
 241  Other tags are also avaible, here is a complete list of all tags for this module :
 242
 243  all
 244  int
 245  double
 246  char
 247
 248  For more informations on the functions, we refer you to the GSL offcial documentation: http://www.gnu.org/software/gsl/manual/html_node/
 249  Tip : search on google: site:http://www.gnu.org/software/gsl/manual/html_node/name_of_the_function_you_want

 251 =head1 EXAMPLES
 252
 253  Most of the examples from this section are perl versions of the examples there : http://www.gnu.org/software/gsl/manual/html_node/Example-programs-for-matrices.html
 254
 255  The program below shows how to allocate, initialize and read from a matrix using the functions gsl_matrix_alloc, gsl_matrix_set and gsl_matrix_get.
 256
 257  use Math::GSL::Matrix qw/:all/;
 258  $m = gsl_matrix_alloc (10,3);
 259  for($i = 0; $i< 10; $i++){
 260     for($j = 0; $j<3; $j++){
 261         gsl_matrix_set($m, $i, $j, 0.23 + 100*$i + $j);
 262     }
 263  }
 264
 265  for($i = 0; $i< 100; $i++){ # OUT OF RANGE ERROR
 266      for($j=0; $j<3; $j++){
 267         print "m($i, $j) = " . gsl_matrix_get ($m, $i, $j) . "\n";
 268     }
 269  }
 270  gsl_matrix_free ($m);
 271
 272
 273  use Math::GSL::Matrix qw/:all/;
 274
 275  $m = gsl_matrix_alloc (100, 100);
 276  $a = gsl_matrix_alloc (100, 100);
 277
 278  for($i = 0; $i < 100; $i++){
 279      for($j = 0; $j < 100; $j++){
 280          gsl_matrix_set ($m, $i, $j, 0.23 + $i + $j);
 281      }
 282  }
 283
 284  The next program shows how to write a matrix to a file.
 285
 286  $out = fopen("test.dat", "wb");
 287  gsl_matrix_fwrite ($out, $m);
 288  fclose ($out);
 289
 290  $in = fopen("test.dat", "rb");
 291  gsl_matrix_fread ($in, $a);
 292  fclose($in);
 293
 294  $k=0;
 295  for($i = 0; $i < 100; $i++){
 296      for($j = 0; $j < 100; $j++){
 297          $mij = gsl_matrix_get ($m, $i, $j);
 298          $aij = gsl_matrix_get ($a, $i, $j);
 299          if ($mij != $aij){ $k++ };
 300      }
 301  }
 302
 303  gsl_matrix_free($m);
 304  gsl_matrix_free($a);
 305
 306  print "differences = $k (should be zero)\n";
