Struct Matrix3x3 

pub struct Matrix3x3 {
    pub data: [f64; 9],
}

A 3x3 matrix stored in row-major order.

Fields

data: [f64; 9]

The 9 elements of the matrix in row-major order.

Implementations

impl Matrix3x3

pub fn new(data: [f64; 9]) -> Self

Create a new 3x3 matrix from row-major data.

pub fn identity() -> Self

Create the 3x3 identity matrix.

pub fn zero() -> Self

Create a zero 3x3 matrix.

pub fn at(&self, r: usize, c: usize) -> f64

Get the element at row r and column c.

pub fn set(&mut self, r: usize, c: usize, val: f64)

Set the element at row r and column c.

pub fn transpose(&self) -> Self

Compute the transpose of this matrix.

pub fn determinant(&self) -> f64

Compute the determinant of this matrix.

pub fn multiply(&self, other: &Self) -> Self

Multiply this matrix by another 3x3 matrix.

pub fn multiply_vec(&self, v: &[f64; 3]) -> [f64; 3]

Multiply this matrix by a 3-vector, returning a 3-vector.

pub fn frobenius_norm(&self) -> f64

Compute the Frobenius norm of the matrix.

Trait Implementations

impl Clone for Matrix3x3

fn clone(&self) -> Matrix3x3

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Matrix3x3

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

Formats the value using the given formatter.

impl PartialEq for Matrix3x3

fn eq(&self, other: &Matrix3x3) -> 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.
