Creating a matrix

using faer_core::mat;

let a = mat![
    [1.0, 2.0, 3.0],
    [4.0, 5.0, 6.0],
];

assert_eq!(a.nrows(), 2);
assert_eq!(a.ncols(), 3);

assert_eq!(a[(1, 2)], 6.0);

Adding two matrices

using faer_core::mat;

let a = mat![
    [1.0, 2.0, 3.0],
    [4.0, 5.0, 6.0],
];
let b = mat![
    [7.0, 8.0, 9.0],
    [10.0, 11.0, 12.0],
];

let mut sum = mat![
    [0.0, 0.0, 0.0],
    [0.0, 0.0, 0.0],
];

sum
    .as_mut()
    .cwise()
    .zip(a.as_ref())
    .zip(b.as_ref())
    .for_each(|sum, a, b| *sum = a + b);

Multiplying two matrices

using faer_core::{mat, mul::matmul, Conj, Parallelism};

let a = mat![
    [1.0, 2.0, 3.0],
    [4.0, 5.0, 6.0],
];
let b = mat![
    [7.0, 8.0],
    [9.0, 10.0],
    [11.0, 12.0],
];

let mut mul = mat![
    [0.0, 0.0],
    [0.0, 0.0],
];

matmul(
    mul.as_mut(),
    Conj::No,
    a.as_ref(),
    Conj::No,
    b.as_ref(),
    Conj::No,
    None,
    1.0,
    Parallelism::None
);
