Struct Complex 

pub struct Complex {
    pub real: f64,
    pub imag: f64,
}

Complex number representation for FFT

This struct provides basic complex arithmetic operations needed for Fast Fourier Transform algorithms. It includes addition, multiplication, and scaling operations optimized for FFT usage.

Fields

real: f64

The real part of the complex number

imag: f64

The imaginary part of the complex number

Implementations

impl Complex

pub const fn new(real: f64, imag: f64) -> Self

Create a new complex number

Arguments

• real - The real part
• imag - The imaginary part

Returns

A new Complex number with the specified real and imaginary parts

pub const fn from_real(real: f64) -> Self

Create a complex number from a real number

Arguments

• real - The real value to convert

Returns

A complex number with the real value and zero imaginary part

pub fn add(self, other: Self) -> Self

Complex addition

Arguments

• other - The complex number to add

Returns

The sum of self and other

pub fn sub(self, other: Self) -> Self

Complex subtraction

Arguments

• other - The complex number to subtract

Returns

The difference of self and other

pub fn mul(self, other: Self) -> Self

Complex multiplication

Arguments

• other - The complex number to multiply

Returns

The product of self and other

pub fn scale(self, scalar: f64) -> Self

Scalar multiplication

Arguments

• scalar - The real number to multiply by

Returns

The complex number scaled by the scalar

pub fn exp(_angle: f64) -> Self

Fallback for no_std - requires std feature

This function is not available in no_std environments and will panic. Use the std feature to enable FFT functionality.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Complex

fn fmt(&self, f: &mut Formatter<'_>) -> Result
