lalgebra_vector
Instructions
A vector in linear algebra is defined as "anything that can be added and that can be multiplied by a scalar"
Define the associated function dot
that calculates the dot product between two vectors
The dot product between two vectors of different length it's not defined
Note: Vector
must implement Debug, Clone, Eq, PartialEq.
Important
Note that in the addition of vector of the example the Rhs
is not Self
Expected Functions and Structure
pub struct Vector<T: Scalar>(pub Vec<T>);
use std::ops::Add;
impl Add for Vector<T> {
}
impl Vector<T> {
pub fn new() -> Self {
}
pub fn dot(&self, other: &Self) -> Option<T> {
}
Usage
Here is a program to test your function.
use lalgebra_vector::*;
fn main() {
let vector_1: Vector<i64> = Vector(vec![1, 3, -5]);
let vector_2: Vector<i64> = Vector(vec![4, -2, -1]);
println!("{:?}", vector_1.dot(&vector_2));
println!("{:?}", vector_1 + &vector_2);
}
And its output:
student@ubuntu:~/[[ROOT]]/test$ cargo run
Some(3)
Some(Vector([5, 1, -6]))
student@ubuntu:~/[[ROOT]]/test$
