EXAMPLES
This code defines $z as 6 + 4*I, takes the complex conjugate of that number, then prints it out.
my $z = gsl_complex_rect(6,4);
my $y = gsl_complex_conjugate($z);
my ($real, $imag) = gsl_parts($y);
print "z = $real + $imag*I\n";
This code defines $z as 5 + 3*I, multiplies it by 2 and then prints it out.
my $x = gsl_complex_rect(5,3);
my $z = gsl_complex_mul_real($x, 2);
my $real = gsl_real($z);
my $imag = gsl_imag($z);
print "Re(\$z) = $real\n";
