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.
