 189 You have to add the functions you want to use inside the qw /put_funtion_here /. You can also write use Math::GSL::PowInt qw/:name_of_tag/ to use all avaible functions of the module. Other tags are also avaible, here is a complete list of all tags for this module :
 190
 191 all
 192 int
 193 double
 194 char
 195
 196 For more informations on the functions, we refer you to the GSL offcial documentation: http://www.gnu.org/software/gsl/manual/html_node/
 197 Tip : search on google: site:http://www.gnu.org/software/gsl/manual/html_node/ name_of_the_function_you_want

 204 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.
 205
 206 use Math::GSL::Matrix qw/:all/;
 207 $m = gsl_matrix_alloc (10,3);
 208 for($i = 0; $i< 10; $i++){
 209         for($j = 0; $j<3; $j++){
 210         gsl_matrix_set($m, $i, $j, 0.23 + 100*$i + $j);
 211         }
 212 }
 213 for($i = 0; $i< 100; $i++){ # OUT OF RANGE ERROR
 214         for($j=0; $j<3; $j++){
 215         print "m($i, $j) = " . gsl_matrix_get ($m, $i, $j) . "\n";;
 216         }
 217 }
 218 gsl_matrix_free ($m);
 219
 220
 221 use Math::GSL::Matrix qw/:all/;
 222 $m = gsl_matrix_alloc (100, 100);
 223 $a = gsl_matrix_alloc (100, 100);
 224
 225 for($i = 0; $i < 100; $i++){
 226         for($j = 0; $j < 100; $j++){
 227         gsl_matrix_set ($m, $i, $j, 0.23 + $i + $j);
 228         }
 229 }
 230
 231 The next program shows how to write a matrix to a file.
 232
 233 $out = fopen("test.dat", "wb");
 234 gsl_matrix_fwrite ($out, $m);
 235 fclose ($out);
 236
 237 $in = fopen("test.dat", "rb");
 238 gsl_matrix_fread ($in, $a);
 239 fclose($in);
 240
 241 $k=0;
 242 for($i = 0; $i < 100; $i++){
 243         for($j = 0; $j < 100; $j++){
 244         $mij = gsl_matrix_get ($m, $i, $j);
 245         $aij = gsl_matrix_get ($a, $i, $j);
 246         if ($mij != $aij){ $k++ };
 247         }
 248 }
 249
 250 gsl_matrix_free($m);
 251 gsl_matrix_free($a);
 252
 253 print "differences = $k (should be zero)\n";
