Struct Svd3 

pub struct Svd3 {
    pub u: Mat3,
    pub s: Vec3,
    pub vt: Mat3,
}

The SVD of a 3x3 matrix (f32 precision).

Fields

u: Mat3

The left orthogonal matrix U.

s: Vec3

The singular values (diagonal entries of S), sorted in descending order.

vt: Mat3

The transposed right orthogonal matrix V^T.

Implementations

impl Svd3

pub fn new(u: Mat3, s: Vec3, vt: Mat3) -> Self

Creates a new SVD from components.

pub fn from_matrix(a: Mat3) -> Self

Computes the SVD of a 3x3 matrix.

Returns the decomposition M = U * S * V^T where:

• U is an orthogonal matrix (left singular vectors as columns)
• S is a diagonal matrix (stored as a vector of singular values)
• V^T is the transpose of an orthogonal matrix

The singular values are sorted in descending order (s.x >= s.y >= s.z).

pub fn recompose(&self) -> Mat3

Rebuilds the matrix this SVD is the decomposition of.

Returns U * S * V^T.

Trait Implementations

impl Clone for Svd3

fn clone(&self) -> Svd3

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Svd3

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

Formats the value using the given formatter.

impl From<DSvd3> for Svd3

fn from(svd: DSvd3) -> Self

Converts to this type from the input type.

impl From<Svd3> for DSvd3

fn from(svd: Svd3) -> Self

Converts to this type from the input type.

impl From<Svd3> for Svd3A

fn from(svd: Svd3) -> Self

Converts to this type from the input type.

impl From<Svd3A> for Svd3

fn from(svd: Svd3A) -> Self

impl PartialEq for Svd3

fn eq(&self, other: &Svd3) -> 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.
