    pub m11: f64,
    pub m12: f64,
    pub m21: f64,
    pub m22: f64,
}

Fields

m11: f64

Row 1, column 1.

m12: f64

Row 1, column 2.

m21: f64

Row 2, column 1.

m22: f64

Row 2, column 2.

Implementations

impl Matrix2

pub const fn new(m11: f64, m12: f64, m21: f64, m22: f64) -> Self

Creates a 2×2 matrix from row-major entries.

pub const fn identity() -> Self

Returns the identity matrix.

pub const fn transpose(self) -> Self

Returns the transpose.

pub const fn determinant(self) -> f64

Returns the determinant.

pub const fn trace(self) -> f64

Returns the trace.

pub const fn mul_vector(self, vector: Vector2) -> Vector2

Returns the matrix-vector product.

pub const fn mul_matrix(self, rhs: Self) -> Self

Returns the matrix-matrix product.

pub fn solve(self, rhs: Vector2) -> Result<Vector2, LinearError>

Solves self * x = rhs for x.

Errors

Returns LinearError::SingularMatrix when the determinant is zero.

Trait Implementations

impl Clone for Matrix2

fn clone(&self) -> Matrix2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Matrix2

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

Formats the value using the given formatter.

impl Default for Matrix2

fn default() -> Matrix2

Returns the “default value” for a type.

impl Mul<Vector2> for Matrix2

type Output = Vector2

The resulting type after applying the * operator.

fn mul(self, rhs: Vector2) -> Self::Output

Performs the * operation.

impl Mul for Matrix2

type Output = Matrix2

The resulting type after applying the * operator.

fn mul(self, rhs: Self) -> Self::Output

Performs the * operation.

impl PartialEq for Matrix2

fn eq(&self, other: &Matrix2) -> 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.
