Complex

java.lang.Object
- ch.aplu.util.Complex

```
public class Complex
extends java.lang.Object
```
This is a complex number class with the essential features needed for computations. The real and imaginary parts can be accessed directly for fast operation. (See ComplexImm for an immutable version of a complex number class.) Several of the common complex number operations are provided as static methods. New instances of Complex are returned by these methods. Code from book: Lindsey, Tolliver, Lindblad, "JavaTech, an Introduction to Scientific and Technical Computing with Java" with some minor modifications.
