Struct num::complex::Complex [-] [+] [src]

pub struct Complex<T> {
    pub re: T,
    pub im: T,
}

A complex number in Cartesian form.

Fields

re

Real portion of the complex number

im

Imaginary portion of the complex number

Methods

impl<T: Clone + Num> Complex<T>

fn new(re: T, im: T) -> Complex<T>

Create a new Complex

fn norm_sqr(&self) -> T

Returns the square of the norm (since T doesn't necessarily have a sqrt function), i.e. re^2 + im^2.

fn scale(&self, t: T) -> Complex<T>

Multiplies self by the scalar t.

fn unscale(&self, t: T) -> Complex<T>

Divides self by the scalar t.

impl<T: Clone + Num + Neg<Output=T>> Complex<T>

fn conj(&self) -> Complex<T>

Returns the complex conjugate. i.e. re - i im

fn inv(&self) -> Complex<T>

Returns 1/self

impl<T: Clone + Float> Complex<T>

fn norm(&self) -> T

Calculate |self|

impl<T: Clone + Float + Num> Complex<T>

fn arg(&self) -> T

Calculate the principal Arg of self.

fn to_polar(&self) -> (T, T)

Convert to polar form (r, theta), such that self = r * exp(i * theta)

fn from_polar(r: &T, theta: &T) -> Complex<T>

Convert a polar representation into a complex number.
