MyMatrix

My simple matrix library that can perform fraction operations.

1. Attribute

• Name: MyMatrix.
• Language: Rust, requires version rustc >= 1.75.0.
• Goal: Write a simple matrix library that can perform fraction operations.
• Module: Vector, Matrix
• Style: Follow Rust's official recommended style.
• Test: Using rstest for unit testing and ensure that all tests passed.
• Security: There is no unsafe code block.
• Document: Using cargo doc --open to open documents.

2. Usage

To use it, add the following lines to your Cargo.toml file:

[dependencies]
mymatrix = "0"

Some simple examples:

use mymatrix::*;

// Vector dot product
Vector::from([1, 2, 3]) * Vector::from([4, 5, 6]); // 32
// Vector cross product
Vector::cross(&[1, 2, 3].into(), &[4, 5, 6].into()); // [-3 6 -3]
// Vector scalar product
Vector::from([1, 2]) * pyinrs::Fraction::from((2, 5)); // [2/5 4/5]

// Matrix rank
Matrix::from([[1, 2, 3], [4, 5, 6], [7, 8, 9]]).rank(); // 2
// Matrix determinant
Matrix::from([[1, 2, 3], [4, 5, 6], [7, 8, 0]]).det(); // 27
// Matrix inversion
Matrix::from([[1, 2, 3], [4, 5, 6], [7, 8, 0]]).inv();
