Implementations

impl ARMat

pub fn new(row: i32, clm: i32) -> Self

Allocate a new matrix with specified dimensions

pub fn transpose(&self) -> ARMat

Transpose the matrix

pub fn det(&self) -> f64

Calculate the determinant of a square matrix

pub fn self_inv(&mut self) -> Result<(), &'static str>

Invert the matrix in place using Gauss-Jordan elimination with column shifting

pub fn inv(&self) -> Result<ARMat, &'static str>

Return a new inverted matrix

pub fn tridiagonalize( &mut self, d: &mut [ARdouble], e: &mut [ARdouble], ) -> Result<(), &'static str>

Tridiagonalize symmetric matrix (port of arVecTridiagonalize)

impl ARMat

pub fn ex(&self, mean: &mut [ARdouble]) -> Result<(), &'static str>

pub fn center(&mut self, mean: &[ARdouble]) -> Result<(), &'static str>

pub fn x_by_xt(&self, output: &mut ARMat) -> Result<(), &'static str>

pub fn xt_by_x(&self, output: &mut ARMat) -> Result<(), &'static str>

pub fn ev_create( &self, u: &ARMat, output: &mut ARMat, ev: &mut [ARdouble], ) -> Result<(), &'static str>

pub fn pca_internal( &self, output: &mut ARMat, ev: &mut [ARdouble], ) -> Result<(), &'static str>

Trait Implementations

impl Clone for ARMat

fn clone(&self) -> ARMat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ARMat

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

Formats the value using the given formatter.

impl Default for ARMat

fn default() -> Self

Returns the “default value” for a type.

impl<'a, 'b> Mul<&'b ARMat> for &'a ARMat

fn mul(self, rhs: &'b ARMat) -> Self::Output

Multiplies two matrices (self * rhs). Port of arMatrixMul from mMul.c.

type Output = Result<ARMat, &'static str>

The resulting type after applying the * operator.

impl PartialEq for ARMat

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