matrix_ops
Instructions
In this exercise, you will define some basic matrix operations, Implement traits for Add
and Sub
Remember that two matrices can only be added or subtracted if they have the same dimensions. Therefore, you must handle the possibility of failure by returning an Option<T>
.
You will be reusing your Matrix
and Scalar
structures defined in the matrix and lalgebra_scalar exercises.
Expected Function
impl Add for Matrix {
}
impl Sub for Matrix {
}
Usage
Here is a program to test your function
// Importing Matrix by defining it as a dependency in Cargo.toml
use matrix_ops::*;
fn main() {
let matrix = Matrix(vec![vec![8, 1], vec![9, 1]]);
let matrix_2 = Matrix(vec![vec![1, 1], vec![1, 1]]);
println!("{:?}", matrix + matrix_2);
let matrix = Matrix(vec![vec![1, 3], vec![2, 5]]);
let matrix_2 = Matrix(vec![vec![3, 1], vec![1, 1]]);
println!("{:?}", matrix - matrix_2);
let matrix = Matrix(vec![vec![1, 1], vec![1, 1]]);
let matrix_2 = Matrix(vec![vec![1, 1, 3], vec![1, 1]]);
println!("{:?}", matrix - matrix_2);
let matrix = Matrix(vec![vec![1, 3], vec![9, 1]]);
let matrix_2 = Matrix(vec![vec![1, 1, 3], vec![1, 1]]);
println!("{:?}", matrix + matrix_2);
}
And its output
$ cargo run
Some(Matrix([[9, 2], [10, 2]]))
Some(Matrix([[-2, 2], [1, 4]]))
None
None
