A Clojure core.matrix implementation using NumPy via libpython-clj. numpy-clj
allows you to use an idiomatic Clojure library, while still interoperating with Numpy, SciPy and the entire Python ecosystem.
Try out numpy-clj
in JupyterLab via Binder along with other core.matrix
implementations. Click here or click the 'launch binder' badge above.
numpy-clj
does not directly provide an API, but is instead used by core.matrix
. numpy-clj
extends core.matrix
to translate to equivalent numpy
functions. Include core.matrix
in your project and use the core.matrix API.
If you're new to core.matrix check out matrix-compare to see how to translate common operations from MATLAB and NumPy into core.matrix.
To ensure the numpy-clj
implementation is registered, make sure to require it in your namespace and set it as the current implementation.
(ns your.namespace
(:require [numpy-clj.core]
[core.matrix :as m]))
(m/set-current-implementation :numpy-clj)
(m/array [[0 1 2]] [3 4 5])
=> [[0 1 2] ;; this will be a numpy object
[3 4 5]]
You can also directly interoperate using libpython-clj
and use numpy
functions directly. Read the official documentation to learn more on writing Python in Clojure.
(ns your.namespace
(:require [numpy-clj.core]
[core.matrix :as m]
[libpython-clj.require :refer [require-python]]))
(require-python '[numpy :as np])
(np/linspace 0 10 100)
=> [ 0. 0.1010101 ...
You can include any commit of this project as a git dependency. Copy and paste the sha hash from any commit and add it to your deps.edn
, like below.
{:deps
{brianchevalier/numpy-clj
{:git/url "https://github.com/brianchevalier/numpy-clj"
:sha ""}}}
Note: numpy-clj
currently uses my fork of core.matrix (via GitHub) which adds a deps.edn file. When you run make test
it will automatically checkout my fork of core.matrix
with this change (branch: deps.edn). Make sure to use the :core-matrix
alias to use my branch.

To run the core.matrix compliance tests run the following make rule.
make test
- The continous integration here uses uses GitHub Actions
To test changes against the exact CI environment:
- Install Docker
- Install act (eg. with homebrew:
brew install act
) - Run the following make rule. Warning: This will require an 18GB(!) download but will fully replicate the GitHub Actions environment
