_

_imaginary. Variable in class Complex

_real. Variable in class Complex

C

clone(). Method in class Complex

Clone procedure

Complex(). Constructor for class Complex

Default constructor creates the complex number z = (0,0)

Complex(double, double). Constructor for class Complex

Creates the complex number z = (real, imaginary)

conjugate(). Method in class Complex

For any complex number z = (a,b) the conjugate (usually denoted z-bar) is defined as (a,-b)

D

divide(Complex). Method in class Complex

Dividing two complex numbers z = (a,b) w = (c,d) is defined as z * w-bar / |w|^2 The |w|^2 is equivalent to w * w.conjugate() where the conjugate of w = (c,d) is defined as (c,-d) Note that multiplying by the conjugate produces a non-negative real number so that we can easily divide the real and imaginary components of the imaginary numbers.

E

equals(Complex). Method in class Complex

Two complex numbers are equal if and only if both their real and imaginary components are equal

equals(Object). Method in class Complex

Two complex numbers are equal if both their real and imaginary components are equal

G

getImaginary(). Method in class Complex

Returns the imaginary component of the complex number

getReal(). Method in class Complex

Returns the real component of the complex number

M

main(String[]). Static method in class Complex

Tests the Complex API

minus(Complex). Method in class Complex

Subtracting two complex numbers (a,b) (c,d) is defined as (a - c, b -d)

P

plus(Complex). Method in class Complex

Adding two complex numbers (a,b) (c,d) is defined as (a+c,b+d)

power(int). Method in class Complex

Return the exponant of the complex number.

T

times(Complex). Method in class Complex

Multiplying two complex numbers (a,b) (c,d) is defined as (a*c - b*d, a*d + b*c)

toString(). Method in class Complex

Returns

(r,i)

where r is the real component and i is the imaginary component
