pub struct Matrix<T> { /* fields omitted */ }

Matrix elements structure

TODO: add overview about matrix here.

1. how to create a matrix
2. Matrix operation
3. Indexing, etc.

Methods

impl<T> Matrix<T>

pub fn shape(&self) -> [usize; 2]

The shape of the matrix [nrows, ncols].

Examples

let m = matrix![
    3.0, 1.0;
    4.0, 1.0;
    5.0, 9.0;
];
assert_eq!(m.shape(), [3, 2]);

impl<T> Matrix<T> where
    T: FromPrimitive + Num + Copy, 

pub fn full(shape: [usize; 2], value: T) -> Matrix<T>

pub fn zeros(shape: [usize; 2]) -> Matrix<T>

pub fn zeros_like(m: &Matrix<T>) -> Matrix<T>

pub fn ones(shape: [usize; 2]) -> Matrix<T>

pub fn ones_like(m: &Matrix<T>) -> Matrix<T>

pub fn from_vec(elements: Vec<Vec<T>>) -> Matrix<T>

impl<U> Matrix<U> where
    U: SampleUniform, 

pub fn uniform(shape: [usize; 2], low: U, high: U) -> Matrix<U>

impl Matrix<f64>

pub fn normal(shape: [usize; 2], mean: f64, std_dev: f64) -> Matrix<f64>

Trait Implementations

impl<T> PartialEq<Matrix<T>> for Matrix<T> where
    T: Num + Copy, 

fn eq(&self, other: &Matrix<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Matrix<T>) -> bool

This method tests for !=.

impl<T: Debug> Debug for Matrix<T>

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

Formats the value using the given formatter.
