The Matrix and ndarray

What is ndarray and why it’s useful

The Rust crate ndarray is used to work with arrays. It covers all the classic uses of an array-handling framework, such as numpy for Python.

Some use cases that are not covered by the main crate are covered by corollary crates, such as ndarray-linalg for linear algebra, ndarray-rand to generate randomness, and ndarray-stats for statistics.

Additionally, ndarray also has some nice extra features. These include support for rayon for parallelization and the popular BLAS low-level specs, through one of the working backends (using blas-src).

We can add ndarray to our project with the following command in Cargo.toml:

[dependencies]
ndarray = "0.14.0"
