Quick start

Add matten to your Cargo.toml:

matten = "0.48.0"

Then:

#![allow(unused)]
fn main() {
use matten::Tensor;

let a = Tensor::new(vec![1.0, 2.0, 3.0, 4.0], &[2, 2]);
let b = Tensor::ones(&[2, 2]);
let c = &a + &b;
println!("{c}");
// 2.0 3.0
// 4.0 5.0
}

The default profile includes serde, JSON (Tensor::from_json), and CSV (Tensor::from_csv) — see Boundary integration for those.

Lean core only

If you don’t need JSON/CSV/serde, opt into the smaller dependency footprint:

matten = { version = "0.48.0", default-features = false }

On this profile, Tensor::from_json / Tensor::from_csv are not available. See Cargo features for the full feature list.
