= Matlab for Nix users
This repo is a collection of files that should help Nix and NixOS users install matlab imperatively.
== How to use this
=== Installation of matlab itself
==== Run `matlab-shell` with +++<s>stable</s>+++ legacy Nix
==== Run `matlab-shell` with an unstable Nix
=== Adding `matlab` executables to your system
==== For NixOS users with a flakes setup
==== For NixOS users without a flakes setup
==== Home Manager setup
== Previous work
TODO:: Add links to tviti's repo etc.
