matrix

Instructions

Define a data structure to represent a matrix of any size and implement the basic operations for this you will need to follow the next steps:

You can use a 2 dimensional Vec's We will consider a matrix as a rectangular arrangements of scalars.

You have to use the definition of scalars done in the last exercise: lalgebra_scalar

Then define the associated function identity that returns the identity matrix of size n

And the associated function zero that returns a matrix of size row x col with all the positions filled by zeroes

Traits

Expected Functions and Structure

pub struct Matrix<T>(pub Vec<Vec<T>>);

impl Matrix<T> {
	pub fn new() -> Matrix<T> {
	}

	pub fn zero(row: usize, col: usize) -> Matrix<T> {
	}

	pub fn identity(n: usize) -> Matrix<T> {
	}
}

Usage

Here is a program to test your function.

fn main() {
	let m: Matrix<u32> = Matrix(vec![vec![0, 0, 0, 0], vec![0, 0, 0, 0], vec![0, 0, 0, 0]]);
	println!("{:?}", m);
	println!("{:?}", Matrix::<i32>::identity(4));
	println!("{:?}", Matrix::<f64>::zero(3, 4));
}

And its output

student@ubuntu:~/[[ROOT]]/test$ cargo run
Matrix([[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]])
Matrix([[1, 0, 0, 0], [0, 1, 0, 0], [0, 0, 1, 0], [0, 0, 0, 1]])
Matrix([[0, 0, 0, 0], [0, 0, 0, 0], [0, 0, 0, 0]])
