vectrix

A stack-allocated, constant-size [Matrix<T, M, N>] type implemented with const generics.

This crate works on stable Rust from v1.51 onwards. It is pretty experimental right now and does not have the same level of features as others like it in the Rust ecosystem. But it useful for quick and dirty use cases, like Advent of Code. Contributions are welcome!

Features

• Generic matrix and vector types.
• matrix! / vector! macros that can be used in const contexts.
• Element access using usize and (usize, usize) indexing.
• Component access for small vectors (.x, .y, etc.).
• Row and column views of matrices.
• Iteration over elements, rows, and columns.
• Implementations of scalar operands for any size vectors and matrices.
• Implementations of addition, subtraction, and multiplication for appropriately sized vectors and matrices.
• And more ... see the full documentation.

Example usage

The following demonstrates matrix multiplication.

```rust use vectrix::{matrix, row_vector, vector};

let v1 = vector![1, 2, 3]; // same as matrix![1; 2; 3] let v2 = row_vector![4, 5, 6]; // same as matrix![4, 5, 6]

asserteq!( v1 * v2, matrix![ 4, 5, 6; 8, 10, 12; 12, 15, 18; ] ); asserteq!(v2 * v1, matrix![32]); ```
