Matx

A lightweight, rusty matrix library that allows for simple and fast matrix operations.

Usage

Creating matrices

Declaring a matrix is rather straightforward: you only need to specify the type of elements, the number of rows and the number of columns.

let mut a_ = Matrix::<f64, 2, 3>::new();

By default, using Matrix::new() will initialize the matrix with zeros. If needed, you can specify the whole content of the matrix using Matrix::from<Vec<Vec<T>>>(), so with a vector of vectors (with each representing a row).

// 1 2 3
// 4 5 6
let a = Matrix::<f64, 2, 3>::from(vec![
        vec![1.0f64, 2.0f64, 3.0f64],
        vec![4.0f64, 5.0f64, 6.0f64]
    ]);

Operators

Multiplication and addition are implemented between matrices, and between a matrix and an object of type T (the type of the elements).
Matrix-matrix operations may require compatibility between the two (sizewise), so they return a Result<>.

No operation is done in-place: they all generate a new matrix.

let c = (a + b).unwrap(); // adds matrices a and b, as long as they are the same size
