• This example shows how to do basic math with complex numbers:

  ComplexDouble x(L"1+1j"), y(L"2+3j"), z(L"3+4j"), ans;
  ans = (x * y + z) / (x + y);

  Basic math is fairly straightforward though casting is sometimes required for mixed types.
  
  
• This example shows how to write a ComplexDouble object into an Sof file:

  ComplexDouble val0(5.0, 0);
  String tmp_filename(L"foo");
  Sof tmp_file;
  tmp_file.open(tmp_filename, File::WRITE_ONLY, File::TEXT);
         
  val0.write(tmp_file, (long)0);
  tmp_file.close();

• This example shows how to generate a random number:

  ComplexDouble rand_num;
  ComplexDouble value;
  ComplexDouble value1;
         
  // using default seed
  //
  value = rand_num.rand();
       
  // Gaussian random number generation
  //
  ComplexDouble mean(5.2, 0.2);
  ComplexDouble std_dev(3.2, 0.7);
  value1 = rand_num.grand(mean, std_dev);
