Struct Matrix3x2 

pub struct Matrix3x2 {
    pub e11: f64,
    pub e12: f64,
    pub e21: f64,
    pub e22: f64,
    pub e31: f64,
    pub e32: f64,
}

A struct representing a 3x2 matrix.

This struct is used to store the transformation matrix for transforming a 2D vector into a 3D vector.

Namely, it is used in the transform_pqw_vector method to tilt a 2D position into 3D, using the orbital parameters.

Each element is named eXY, where X is the row and Y is the column.

Example

use glam::{DVec2, DVec3};

use keplerian_sim::Matrix3x2;

let matrix = Matrix3x2 {
   e11: 1.0, e12: 0.0,
   e21: 0.0, e22: 1.0,
   e31: 0.0, e32: 0.0,
};

let vec = DVec2::new(1.0, 2.0);

let result = matrix.dot_vec(vec);

assert_eq!(result, DVec3::new(1.0, 2.0, 0.0));

Fields

e11: f64

e12: f64

Implementations

impl Matrix3x2

pub const ZERO: Self

The zero matrix.

Multiplying a vector with this results in a vector of zero length.

pub const IDENTITY: Self

The identity matrix.

Multiplying a vector with this results in the same vector.

pub fn dot_vec(&self, vec: DVec2) -> DVec3

Computes a dot product between this matrix and a 2D vector.

Example

use glam::{DVec2, DVec3};

use keplerian_sim::Matrix3x2;

let matrix = Matrix3x2 {
    e11: 1.0, e12: 0.0,
    e21: 0.0, e22: 1.0,
    e31: 1.0, e32: 1.0,
};

let vec = DVec2::new(1.0, 2.0);

let result = matrix.dot_vec(vec);

assert_eq!(result, DVec3::new(1.0, 2.0, 3.0));

Trait Implementations

impl Clone for Matrix3x2

fn clone(&self) -> Matrix3x2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Matrix3x2

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

Formats the value using the given formatter.

impl Default for Matrix3x2

fn default() -> Matrix3x2

Returns the “default value” for a type.

impl PartialEq for Matrix3x2

fn eq(&self, other: &Matrix3x2) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
