Struct PrincipalAxes 

pub struct PrincipalAxes {
    pub major_variance_m2: f64,
    pub minor_variance_m2: f64,
    pub major_heading_rad: f64,
}

The axes of a Covariance: its eigenvalues, and the heading of the larger one’s eigenvector.

Fields

major_variance_m2: f64

The variance along the major axis, the larger eigenvalue λ₁, m².

minor_variance_m2: f64

The variance along the minor axis, the smaller eigenvalue λ₂, m²; zero for points on a line.

major_heading_rad: f64

The major axis’s heading, clockwise from north, in [0, π); east’s, π/2, for a circle.

Trait Implementations

impl Clone for PrincipalAxes

fn clone(&self) -> PrincipalAxes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PrincipalAxes

impl Debug for PrincipalAxes

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PrincipalAxes

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PrincipalAxes

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

impl Serialize for PrincipalAxes

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
