Struct Matrix2x2 

pub struct Matrix2x2 { /* private fields */ }

Matrice 2×2 en f32, stockée en row-major.

use embedded_matrix::Matrix2x2;

let m = Matrix2x2::new([[1.0, 2.0], [3.0, 4.0]]);
assert!((m.det() - (-2.0)).abs() < 1e-5);

Implementations

impl Matrix2x2

pub const fn new(data: [[f32; 2]; 2]) -> Self

Crée une matrice à partir d’un tableau row-major.

pub const fn identity() -> Self

Matrice identité.

pub const fn zero() -> Self

Matrice nulle.

pub fn get(&self, row: usize, col: usize) -> f32

Retourne l’élément à la ligne row et colonne col (0-indexé).

pub fn as_array(&self) -> &[[f32; 2]; 2]

Donne accès aux données brutes row-major.

pub fn add(&self, rhs: &Self) -> Self

Addition terme à terme.

pub fn sub(&self, rhs: &Self) -> Self

Soustraction terme à terme.

pub fn mul(&self, rhs: &Self) -> Self

Produit matriciel standard.

pub fn scale(&self, s: f32) -> Self

Multiplication par un scalaire.

pub fn transpose(&self) -> Self

Transposée.

pub fn det(&self) -> f32

pub fn inv(&self) -> Result<Self, MatrixError>

Inverse de la matrice.

Retourne Err(MatrixError::SingularMatrix) si le déterminant est nul (seuil : |det| < 1e-7).

Trait Implementations

impl Add for Matrix2x2

a + b → addition terme à terme.

type Output = Matrix2x2

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self

Performs the + operation.

impl Clone for Matrix2x2

fn clone(&self) -> Matrix2x2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Matrix2x2

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

Formats the value using the given formatter.

impl Mul<f32> for Matrix2x2

a * s → multiplication par un scalaire f32.

type Output = Matrix2x2

The resulting type after applying the * operator.

fn mul(self, s: f32) -> Self

impl Mul for Matrix2x2

a * b → produit matriciel.

type Output = Matrix2x2

The resulting type after applying the * operator.

impl Neg for Matrix2x2

-a → négation terme à terme.

type Output = Matrix2x2

The resulting type after applying the - operator.

fn neg(self) -> Self

Performs the unary - operation.

impl PartialEq for Matrix2x2

fn eq(&self, other: &Matrix2x2) -> 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.

a - b → soustraction terme à terme.

type Output = Matrix2x2

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self

Performs the - operation.

impl Copy for Matrix2x2
