Struct artha::matrix::Matrix

pub struct Matrix<T> {
    pub dim: (usize, usize),
    // some fields omitted
}

A 2D generic Matrix with Vec<Vec<T>> as underlying data structure

Fields

dim: (usize, usize)

Methods

impl<T> Matrix<T>

pub fn new() -> Self

Creates a new Matrix

pub fn dot(&self, another: &Matrix<T>) -> Result<Matrix<T>, Box<dyn Error>> where
    T: Mul + AddAssign + AddAssign<<T as Mul>::Output> + Copy + Default + Debug, 

Computes the dot product of this matrix with another i.e matrix multiplication

pub fn transpose(&self) -> Matrix<T> where
    T: Default + Debug + Copy, 

Returns the tranpose of the given Matrix

pub fn max(&self) -> Result<Vec<T>, Box<dyn Error>> where
    T: PartialOrd + Default + Copy, 

Finds the maximum of each column in the matrix and returns them as Vec

Methods from Deref<Target = Vec<Vec<T>>>

pub fn capacity(&self) -> usize

Returns the number of elements the vector can hold without reallocating.

Examples

let vec: Vec<i32> = Vec::with_capacity(10);
assert_eq!(vec.capacity(), 10);

pub fn as_slice(&self) -> &[T]

Extracts a slice containing the entire vector.

Equivalent to &s[..].

Examples

use std::io::{self, Write};
let buffer = vec![1, 2, 3, 5, 8];
io::sink().write(buffer.as_slice()).unwrap();

pub fn len(&self) -> usize

Returns the number of elements in the vector, also referred to as its 'length'.

Examples

let a = vec![1, 2, 3];
assert_eq!(a.len(), 3);

pub fn is_empty(&self) -> bool

Returns true if the vector contains no elements.

Examples

let mut v = Vec::new();
assert!(v.is_empty());

v.push(1);
assert!(!v.is_empty());
