Source

type VectorType

Required Methods§

Source

fn zeros() -> Self::MatrixType

Create a matrix filled with zeros

Source

fn ones() -> Self::MatrixType

Create a matrix filled with ones

Source

fn identity() -> Self::MatrixType

Create the identity matrix

Source

fn copy_to(&self, dst: &mut Self::MatrixType)

Copy values to another matrix

Source

fn transpose(&mut self) -> &mut Self::MatrixType

Compute the transpose of this matrix

Source

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

Perform matrix-multiplication with the given right-hand-side operand

Source

fn mul_vector(&self, rhs: &[f32]) -> Self::VectorType

Multiplies this matrix with the given right-hand-side vector, i.e. Matrix * rhs

Depending on dimensionality, the homogenous coordinate can be omitted, if so, it will be assumed to be equal to 1.

Source

fn mul_vector_left(&self, lhs: &[f32]) -> Self::VectorType

Multiplies the given row vector with this matrix, i.e. lhs * Matrix

Depending on dimensionality, the homogenous coordinate can be omitted, if so, it will be assumed to be equal to 1.

Source

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

Perform element-wise addition with the given right-hand-side operand

Source

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

Perform element-wise substraction with the given right-hand-side operand

Source

fn scale(&mut self, factor: f32) -> &mut Self::MatrixType

Scale the matrix elment-wise by the given constant

Source

fn inverse(&mut self) -> Option<&mut Self::MatrixType>

Compute the inverse of this matrix. Returns None if it is singular.

Source

fn det(&self) -> f32

Compute the determinant of this matrix.

Source

fn adjugate(&mut self) -> &mut Self::MatrixType

Compute the adjugate of this matrix

Source

fn translate(&mut self, direction: &[f32]) -> &mut Self::MatrixType

Translate this matrix into the given direction

Depending on dimensionality, the homogenous coordinate of direction can be omitted, if so, it will be assumed to be equal to 1.

Source

fn rotate(&mut self, angle: f32, axis: &[f32]) -> &mut Self::MatrixType

Rotate this matrix by the given angle (radians) around the given axis

Depending on dimensionality, the homogenous coordinate of axis can be omitted, if so, it will be assumed to be equal to 1.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
