Struct Svd2 

pub struct Svd2 {
    pub u: Mat2,
    pub s: Vec2,
    pub vt: Mat2,
}

The SVD of a 2x2 matrix (f32 precision).

Fields

u: Mat2

The left orthogonal matrix U.

s: Vec2

The singular values (diagonal entries of S).

vt: Mat2

The transposed right orthogonal matrix V^T.

Implementations

impl Svd2

pub fn new(u: Mat2, s: Vec2, vt: Mat2) -> Self

Creates a new SVD from components.

pub fn from_matrix(m: Mat2) -> Self

Computes the SVD of a 2x2 matrix.

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

• U is an orthogonal matrix
• 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).

pub fn recompose(&self) -> Mat2

Rebuilds the matrix this SVD is the decomposition of.

Returns U * S * V^T.

Trait Implementations

impl Clone for Svd2

fn clone(&self) -> Svd2

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Svd2

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

Formats the value using the given formatter.

impl From<DSvd2> for Svd2

fn from(svd: DSvd2) -> Self

Converts to this type from the input type.

impl From<Svd2> for DSvd2

fn from(svd: Svd2) -> Self

Converts to this type from the input type.

impl PartialEq for Svd2

fn eq(&self, other: &Svd2) -> 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.
