Crate ferrix

A simple static matrix library for Rust.

This crate implements three main types: Vector, RowVector, and Matrix.

Alongside, various views are implemented to minimize memory allocation and copying.

Common matrix operations are implemented via operator overloading.

• Matrix addition: A + B and A += B
• Matrix subtraction: A - B and A -= B
• Matrix multiplication: A * B

Scalar operations are also supported.

• Scalar addition: A + s and A += s
• Scalar subtraction: A - s and A -= s
• Scalar multiplication: A * s and A *= s
• Scalar division: A / s and A /= s

The DotProduct trait is implemented for Vector and RowVector.

Example

use ferrix::*;

// Initialize a 3x3 matrix
let a = Matrix3::from([
    [1.0, 2.0, 3.0],
    [4.0, 5.0, 6.0],
    [7.0, 8.0, 9.0],
]);

// Initialize a 3x1 column vector
let b = Vector3::from([1.0, 2.0, 3.0]);

// Perform matrix multiplication
let c = a * b;
assert_eq!(c, Matrix::from([[14.0], [32.0], [50.0]]));
