matrix-algebra

lib.rs:

This crate intends to support basic matrix operations and arithmetic. It is quite open in the choice of the underlying scalar type.

For instance, the scalar type can be chosen to be anything that implements common arithmetic traits like Add, Sub, Div, ...

The core types of this crate are Matrix, Scalar and Func. A matrix can created like this:

use matrix_algebra::Matrix;

let m = Matrix::new(vec![vec![0, 1], vec![2, 3]]);

use matrix_algebra::Matrix;

let m1 = Matrix::new(vec![vec![0, 1], vec![2, 3]]);
let m2 = Matrix::new(vec![vec![0, 1], vec![2, 3]]);

assert_eq!(m1 + m2, Matrix::new(vec![vec![0, 2], vec![4, 6]]));

use matrix_algebra::{Matrix, Func};

let sin = Func::new(|x| f64::sin(x));
let m = Matrix::new(vec![vec![0.0, 1.0], vec![2.0, 3.0]]);

assert_eq!(
  sin%m,
  Matrix::new(
   vec![vec![f64::sin(0.0), f64::sin(1.0)], vec![f64::sin(2.0), f64::sin(3.0)]]
  )
);

use matrix_algebra::{Matrix, Scalar};

let m = &Matrix::new(vec![vec![0, 1], vec![2, 3]]);
let s = Scalar(2);

assert_eq!(s*m, m*2);
