nalgebra extension for LaTeX

The crate provides several robust formatters for nalgebra::Matrix as well as several LaTeX environments for customization.

On top of that, the crate offers feature-gated support for nalgebra_linsys and evcxr.

Example

use nalgebra::matrix;
use nalgebra_latex::{
	fmt::{write_latex, PlainMatrixFormatter, LatexFormatter},
	latex_modes::{InlineMathMode, DisplayMathMode, InnerParagraphMode},
};

let mut s = String::new();
let m = matrix!(
	1,2,3,4;
	5,6,7,8;
	9,10,11,12;
);

write_latex::<PlainMatrixFormatter,InnerParagraphMode,InlineMathMode,_,_>(&mut s, &m).unwrap();
assert_eq!(s, r"$\begin{matrix}1&2&3&4\\5&6&7&8\\9&10&11&12\end{matrix}$");
s.clear();
write_latex::<PlainMatrixFormatter,InnerParagraphMode,DisplayMathMode,_,_>(&mut s, &m).unwrap();
assert_eq!(s, r"$$\begin{matrix}1&2&3&4\\5&6&7&8\\9&10&11&12\end{matrix}$$");

What is nalgebra?

nalgebra is a general-purpose linear algebra library with transformations and statically-sized or dynamically-sized matrices.

What is LaTeX?

LaTeX is a language for typesetting documents, especially scientific papers, and a document preparation system.

Warning

The library is overhauled. It changes frequently and the documentation is not always available. Doc tests (examples in the documentation) generally show working code.
