Struct Matrix3x2

pub struct Matrix3x2<T> {
    pub e11: T,
    pub e12: T,
    pub e21: T,
    pub e22: T,
    pub e31: T,
    pub e32: T,
}

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 tilt_flat_position 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 keplerian_sim::Matrix3x2;
 
let matrix: Matrix3x2<f64> = Matrix3x2 {
   e11: 1.0, e12: 0.0,
   e21: 0.0, e22: 1.0,
   e31: 0.0, e32: 0.0,
};
 
let vec = (1.0, 2.0);
 
let result = matrix.dot_vec(vec);
 
assert_eq!(result, (1.0, 2.0, 0.0));

Fields

e11: T

Implementations

impl<T: Copy> Matrix3x2<T>

pub fn filled_with(element: T) -> Matrix3x2<T>

Create a new Matrix3x2 instance where each element is initialized with the same value.

Example

use keplerian_sim::Matrix3x2;
 
let matrix = Matrix3x2::filled_with(0.0);
 
assert_eq!(matrix, Matrix3x2 {
   e11: 0.0, e12: 0.0,
   e21: 0.0, e22: 0.0,
   e31: 0.0, e32: 0.0,
});

impl<T> Matrix3x2<T>

where T: Copy + Mul<Output = T> + Add<Output = T>,

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

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

Example

use keplerian_sim::Matrix3x2;
 
let matrix: Matrix3x2<f64> = Matrix3x2 {
    e11: 1.0, e12: 0.0,
    e21: 0.0, e22: 1.0,
    e31: 1.0, e32: 1.0,
};
 
let vec = (1.0, 2.0);
 
let result = matrix.dot_vec(vec);
 
assert_eq!(result, (1.0, 2.0, 3.0));

Trait Implementations

impl<T: Clone> Clone for Matrix3x2<T>

fn clone(&self) -> Matrix3x2<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Matrix3x2<T>

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

Formats the value using the given formatter.

impl<T: PartialEq> PartialEq for Matrix3x2<T>

fn eq(&self, other: &Matrix3x2<T>) -> 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.
