Full description

1. Emacs MATLAB-mode

MathWorks MATLAB® and GNU Emacs integration:

MATLAB mode, matlab-ts-mode or matlab-mode, for editing *.m files.
- Edit MATLAB code with syntax highlighting and smart indentation.
- Lint MATLAB code with fix-it's using the MATLAB Code Analyzer.
The matlab-ts-mode is a more capable, performant, and accurate than matlab-mode.
Code navigation and more
- The MATLAB Language Server with Emacs, matlabls, provides code navigation, code completion, go to definition, find references, and more.
- Imenu support for quickly jumping to function declarations in the current *.m or *.tlc file. See doc/matlab-imenu.org.
M-x matlab-shell for running and debugging MATLAB within Emacs (Unix only).
- MATLAB command window errors are hyper-linked and files open in Emacs
- Debugging support is available from the MATLAB menu.
- matlab-shell uses company-mode for completions.
See doc/matlab-shell-for-unix.org

M-x matlab-shell to run remote Unix MATLAB within your local Emacs session.

You use Emacs on your local computer to edit files on the remote computer, run and debug remote MATLAB in a matlab-shell in your local Emacs. See doc/remote-matlab-shell.org.

M-x matlab-netshell for running MATLAB code on Microsoft Windows within Emacs using an attached MATLAB.

| (3) Visit script *.m files and use   |         | >> emacsinit                     |
|     "MATLAB -> Code Sections" menu   |         | >>                               |

+--------------------------------------+         +----------------------------------+

Code sections support for MATLAB script files. See doc/matlab-code-sections.org.
- After visiting a MATLAB script, you have a "MATLAB -> Code Sections" menu and key bindings which lets you navigate, run, and move code sections.
- Try out code sections using: ./examples/matlab-sections/tryout_{matlabsection.m}.
Creation of scientific papers, theses, and documents using MATLAB and http://orgmode.org.
- Org enables literate programming which directly supports reproducible research by allowing scientists and engineers to write code along with detailed explanations in natural language.
- You author code plus natural language descriptive text in *.org files. When you evaluate MATLAB or other language code blocks within the *.org files, org inserts the results back into the *.org file.
- You can combine multiple *.org files into one final document, thus enabling larger scientific documents.
- See ./examples/matlab-and-org-mode/ to get started. This directory contains a PDF generated from ./examples/matlab-and-org-mode/matlab-and-org-mode.org.
tlc-mode for editing *.tlc files. The Target Language Compiler (TLC) is part of Simulink® Coder™.

2. Installation

Install the MATLAB package via MELPA or ELPA. MELPA contains the latest version. To install from MELPA, add to your ~/.emacs
```
(require 'package)
(add-to-list 'package-archives '("melpa" . "http://melpa.org/packages/") t)
```
Restart Emacs and then
```
M-x package-install RET matlab-mode RET
```
Note: to all available packages, M-x RET list-packages RET
[Optional] Install the company package which is used for TAB completions.
```
M-x package-install RET company RET
```
[Optional] Install MATLAB tree-sitter for matlab-ts-mode, which provides improved editing capabilities and improved performance.

The MATLAB tree-sitter leverages Tree-sitter to create a parse tree for MATLAB code. The parse tree is updated incrementally and is robust to syntax errors. It is highly performant and achieves this by being implemented in C to create a shared object that is loaded into the Emacs process. matlab-ts-mode leverages the MATLAB tree-sitter to give an improved MATLAB editing experience when compared with matlab-mode.

See doc/install-matlab-tree-sitter-grammar.org
[Optional] Install lsp-mode and the MATLAB Language Server for an improved editing experience.
[Optional] Check your installation setup.

If you are using matlab-ts-mode, visit a *.m MATLAB file and select the menu item:
```
MATLAB -> Check setup
```

News

1. Release 7.1.2 Oct 16, 2025

matlab-is-matlab-file: This function identifies when the content of a *.m file is MATLAB code, if it's not MATLAB code, Emacs defaults to Objective-C. This fixes a case where a *.m contains MATLAB code and the first line is a @function_handle.

2. Release 7.1.1 Oct 1, 2025

matlab-ts-mode: fix semantic movement in strings. Now C-M-f, C-M-b, C-M-SPC work when point is within strings.

3. Release 7.1.0 Sep 29, 2025

Improved matlab-ts-mode imenu. The imenu index now creates indices for code sections defined by "%% heading comments". In addition, the menu was updated to have structure:
- Class
- Function
- Section
Previously, imenu was a flat list without code sections index entries.

4. Release 7.0.1 Sep 13, 2025

emacsrunregion fix, https://github.com/mathworks/Emacs-MATLAB-Mode/pull/55

5. Release 7.0.0 Sep 12, 2025

New matlab-ts-mode.

matlab-ts-mode is a tree-sitter, based MATLAB mode using https://github.com/acristoffers/tree-sitter-matlab. This new MATLAB mode is a replacement for the matlab-mode.
- Improved font-lock (semantic coloring) performance, making editing even more smooth.
  - More accurate fontification, we now identify language elements accurately and use more faces to color them.
  - Fixes edge-case fontification issues when compared with matlab-mode
    
    Create issue for this:
```
x = [1 2; 3 4];
y = x''               % this is valid double transpose where matlab-mode gets it wrong
```
    Function identification, see https://github.com/mathworks/Emacs-MATLAB-Mode/issues/48
  - In comments, we now highlight FIXME, TODO, and XXX markers.
  - Fixed fontification of "%% section" to require that the be the start of a comment and on their own line.
  - Variable creation/assignment will be semantically colored.
  - Now fontify all MATLAB/Simulink factory builtin provided functions, class methods/properties, enums, etc. Note, if you override a builtin function with a variable, the variable creation/assignment will be colored as a variable, but the use will continue to be a function. To avoid this confusing state, use variable names that collide with builtin items.
- Improved indent
  - Simplified the semantics for indent. The indent rules are described in matlab-ts-mode.el for completeness.
  - Improved indent performance, making editing very smooth.
  - Fixes various edge-case indent issues, some are
    - Fixed indent of function definition when ellipsis continuations are used.
    - Auto-indentation of end, see https://github.com/mathworks/Emacs-MATLAB-Mode/issues/33
    - Fixed cell and matrices indent alignment problems
- There's no longer prompting if you want functions to have end's. This is now computed automatically.
- Improved fill-paragraph, M-q, which will now fill comments and when not in a comment, indent the current function or statement.
- Accurate type of m-file detection, which improves matlab-sections-minor-mode.
- Change Log command now work with MATLAB *.m files.
  
  Running C-x 4 a (add-change-log-entry-other-window) will now insert the name of the function or classdef for the current point.
- Added support for M-x outline-minor-mode. Outline headings are function's, classdef's, and "%% heading" comments.
- On save fix of function/classdef name now handles buffer names that aren't valid MATLAB identifiers. On save fix of function/classdef name handles buffers not associated with files on disk. Also fixed cases where detection of scripts failed.
- Improved handling of single quotes for M-x electric-pair-mode. These will automatically pair
