 252 You have to add the functions you want to use inside the qw /put_funtion_here / with spaces between each function. You can also write use Math::GSL::Complex qw/:all/ to use all avaible functions of the module.
 253
 254 For more informations on the functions, we refer you to the GSL offcial documentation: http://www.gnu.org/software/gsl/manual/html_node/

 257 =head1 EXAMPLES
 258
 259 This code defines $z as 6 + 4*I, takes the complex conjugate of that number, then prints it out.
 260
 261     my $z = gsl_complex_rect(6,4);
 262     my $y = gsl_complex_conjugate($z);
 263     my ($real, $imag) = gsl_parts($y);
 264
 265     print "z = $real + $imag*I\n";
 266
 267 This code defines $z as 5 + 3*I, multiplies it by 2 and then prints it out.
 268
 269     my $x = gsl_complex_rect(5,3);
 270     my $z = gsl_complex_mul_real($x, 2);
 271     my $real = gsl_real($z);
 272     my $imag = gsl_real($z);
 273     print "Re(\$z) = $real\n";
