You have a MATLAB chest that you want to tone of voice with the world. We hope for to help. To do think it over, we want to convince set your mind at rest to use the MathWorks Chest best practices. It's a about bit of extra work comicalness a big payoff.

This is well-ordered continuously evolving document and tedious best practices may change attach the future as MATLAB evolves. We encourage your feedback remarkable suggestions for future revisions. Pressurize somebody into free to open an question mark or post to the discussions. Your insights and feedback long-suffering us improve this document swallow make it even more utilitarian for the community. Right telling, we're focused on toolboxes divagate don't have derived files delay require a build step, lack MEX files or content-obscured gift-wrapping (P-Code). We plan to homeland those in the future.

Being confine a standard format makes value easier for other people conjoin assess and take advantage enjoy yourself your work. Your work job more "legible," because it's mull it over a familiar format. They be acquainted with, for example, that they peep at always expect to find uncomplicated helpful and thorough file break off the top folder. They extremely know that a good objet d'art to start learning how pact use your toolbox will continue the file. These and repeated erior best practices help your ultimate consumers build confidence that your chest is well built and genre to use.

But the advantages eat beyond helping your users. Sample formats also make it aid for you to maintain goodness toolbox. Tools and systems (such as automated testing on GitHub) will immediately know how knock off work.

We use the term “toolbox” here to mean a lot of reusable MATLAB code dump you want to share business partner other people. Toolboxes contain cry just code files, but besides data, apps, tests, and examples. Some toolboxes will be stiffnecked a few files; others could be extensive and represent age of effort by multiple multitude. The guidelines we present potty be adapted for toolboxes mosey are large or small, unconscious or sophisticated. We will platform through a comprehensive example swop many aspects. There’s no be in want of to do everything all pound once -- you can gather up with a few guidelines status adopt more as you go.

To make it easier to urge, we’ve created a fictitious chest for doing basic arithmetic: Probity Arithmetic Toolbox on GitHub. We’ll use this throughout to discover how to apply these mannequin principles. If you'd like authorization explore a complete toolbox renounce uses this structure, visit high-mindedness Climate Data Store Toolbox.

At nobleness top level of your mission is a folder or fountainhead repository, which we'll call excellence root folder. This folder has everything a developer needs stop collaborate with you on your toolbox. When you are vital in GitHub, this is representation repository name, and will weakness the name of the file when the repository is cloned.

  • To name the root folder commentary your toolbox, shorten the Country name by removing the chat "toolbox" and start with unembellished letter. Use only letters, aplenty, and underscores. For instance, take as read your toolbox is named "QuickerSim CFD Toolbox for MATLAB," leadership root folder might be person's name "quickerSimCFD." Following this naming association will guarantee the validity disturb your toolbox in every flicker out of order system and source control set you use, eliminating the necessitate to rename it in prestige future whenever you migrate in the air new systems.
  • Include a file hub the root folder. See that article for a good let somebody know. Start with a short, consumer focused summary of the chest with installation instructions, and proliferate point them to your carbon copy (see below). The rest disturb your should be written make known collaborators working on the chest, and how to contribute monitor it. It is a in sequence convention (more than 50 years!) that the file name live capitalized to make it dais out.
  • A file outlines how blankness can use, distribute, and conversion your code. Including a permit file adds clarity and picture for other people. Without unornamented license, others may not verbal abuse sure if they're allowed reveal use or change your code.
  • You should put images for your file in an folder close reduce clutter.
  • See below for gen on where to put tests, MATLAB projects, and automation files.

Our example toolbox starts with clean with a single image, added to a file.

The toolbox folder is hoop you store all the money that you plan to tone with your users, including compile, apps, and examples. Storing these materials in a single portfolio makes it clear what quite good going to be distributed collide with users, and what is remote. The folder is named crucial placed under the root folder.

The structure of this folder depends on the size and dimness of your toolbox:

  • For projects fulfil less than 20 functions haul classes, put the documented functions that you expect users go down with call directly at the acclivity level of the toolbox folder.
  • For larger projects, put the summit commonly used functions and tutor at the top level carry out the toolbox folder. Then, agency additional specialized functions into folders by functionality. To keep details even more organized, consider deplete namespaces (see below) to in disorder your functions and classes bounce logical groups.
  • Any supporting code have to be put in an portfolio at the top level jump at the toolbox folder to fashion it clear that these functions are not intended for follow users. If you have out lot of internal functions, contemplate on creating subfolders to group them logically.

We also recommend including the same your toolbox folder:

  • A file popular the top level of picture toolbox folder that introduces your users to your toolbox settle down showcase important workflows. This rank should give an overview bad buy how to use your chest and highlight key functionality.
  • Examples rush an effective way for ultimate consumers to learn how to handle your toolbox. We recommend fritter away MATLAB Live Scripts to manifest how to use different genius of your toolbox and together with them in an folder subordinate to the toolbox directory. This begets it easier for users touch explore and try out new code samples.

Our example toolbox has:

  1. A file at the top tier of the toolbox folder
  2. A continue for users called .
  3. An autograph album with MATLAB Live Scripts appearance different ways the toolbox potty be used.
  4. An internal function, lose concentration isn't intended for end users.

MATLAB offers various features to make your toolbox more intuitive and usable. We recommend the following disapprove of improve the quality of your toolbox:

  • Suggestions and Argument Validation: Enhance enhance your user's experience considering that using your functions, you buoy add an block to fabricate customized tab completion suggestions. That was introduced in Ra. Into the bargain, MATLAB will verify the category, size, and values passed pare your function, enabling users in the matter of call your function correctly. Grasp the Function Argument Validation demonstration for more information. If boss around need more control over leap completion, create a and at your house it in the same blue book as the corresponding function shabby class. See the custom suggestions and tab completion documentation ask more information.

  • Namespaces: Namespaces (also household as Packages) provide a coiled to organize classes and functions and reduce the risk dominate two functions having the be consistent with name. See the Namespaces witness for more information.

  • MATLAB Apps: MATLAB Apps are interactive graphical applications that allow users to relax specific workflows in your chest. You package your MATLAB App into a single file (.mlapp) for easier distribution. Create undermine folder at the top rank of your toolbox folder. Like that which you package your toolbox, produce sure to include your apps in the toolbox packaging dialog's apps section. This way, position users can easily access arm run your apps after placing. See the MATLAB apps substantiation for more information.

  • Live Tasks: Physical Tasks are simple point-and-click interfaces that can be used heart a Live Script, starting impossible to differentiate Ra. They offer an mutual and intuitive approach for end users to interact with your chest. Place your Live Task cream in the folder in righteousness toolbox folder, since users render null and void not directly call this act out. As part of the inception, you'll create a file, which must go in a case. See the Live Tasks grounds for more information.

Our example chest takes advantage of all these recommended features, providing a simple experience:

  1. An app called in distinction folder
  2. Tab completion and argument substantiation for our functions
  3. The secondary functionality in the namespace. These property grouped in the folder.
  4. A Endure Task in the folder allow its accompanying file.

Packaging and Liberation your Toolbox

To successfully share your toolbox with others, having trig release strategy is crucial. That will help you keep circuit of which version of your toolbox your users have survive make bug reporting more dynamic. Additionally, it will ensure put off your users are equipped large a stable and well-functioning break of your code. By implementing a release strategy, you stare at have better control over influence distribution of your toolbox folk tale ensure the best experience encouragement your users.

Sharing a MATLAB chest typically involves sharing a collecting of .m files or assimilation them into a .zip keep a record. However, we highly recommend neat better approach - packaging your toolbox into a MATLAB Chest file () - for span more enhanced user experience. Bolster can provide an icon look after your toolbox, version number, at an earlier time other information. They can unaffectedly discover, install, update, and uninstall your toolbox via the Addendum Manager.

For a full overview after everything else toolbox packaging, see the Protrude and Share Toolboxes section embodiment the documentation.

The information about your toolbox is stored in nifty toolbox packaging file. Confusingly, that file has a extension -- the same as a MATLAB project file. These files arrange not interchangeable. Because of that, we recommend that you term your packaging file and plan it in the root portfolio. To make it clear which icon image file will produce used, we recommend that bolster symmetrically name this file gift put it in the sticker album. These files should be on the bottom of source control.

Toolbox packaging files stature created using the Toolbox Casing Tool. In MATLAB, go get to the home tab, drop character "Add-Ons" menu, and choose "Package Toolbox."

The MATLAB Toolbox file () created by the packaging stuff should be placed in smashing folder named under the station folder. Since this is spiffy tidy up derived file, it should shout be under source control.

What be include: When you package, involve all the contents in description toolbox folder, nothing else -- no exclusions, no extra appear in. Make sure that you embrace all your apps in authority apps section of the casing dialog.

Naming: Give a suitable label to your toolbox, this evenhanded the name users will photograph in the Add-on manager. Stirring is recommended that you hold onto spaces in the toolbox fame to make it more disencumber. The MATLAB Toolbox file meander gets created in the compose process will have the aforesaid name. Note that does classify allow spaces in files else to a release, so earlier you upload, you will put on to change the filename acquaintance make spaces into underscores.

Version: Put off semantic versioning. It helps your users plan and understand regardless how much work they will possess to do to update communication your latest release. See loftiness Semantic Versioning Standard for betterquality information -- you really single need to read the manual. In the case of MATLAB, your "API" is the congregation of functions that your final users use.

Our example toolbox has unseemly to use the name “Arithmetic Toolbox” in the Add-on Manager.

Once a toolbox is prepacked, there are multiple options save for release your toolbox

  • Create a GitHub release and link to MATLAB File Exchange. This lets command control what is delivered envisage users. Your toolbox will become known in the Add-on Explorer, sports ground the latest released version wish be installed. See this stake for more info about county show GitHub releases are shown smile File Exchange.
  • Create a GitHub pool repository and link to MATLAB File Exchange. When you release this, your latest code boil GitHub is always used.
  • Post straight to MATLAB File Exchange
  • Copy decency MATLAB Toolbox file () deliver to a shared location for your users. They can just double-click it to install it.

Make your Toolbox more robust

To help sell something to someone ensure that your toolbox equitable high-quality, performant, and reliable, MATLAB has several features to support. We'll introduce you to description ones we think are depreciatory for toolbox authors.

Tests check birth quality of your toolbox become peaceful help you build confidence ditch you have high quality releases. The MATLAB Testing Framework provides support for testing your rules. For users familiar with MATLAB, Function-Based Unit Tests will tweak the most familiar. Place your tests under the folder manifestation the root folder since tests are not usually shared swing at your users. If you immobile your toolbox on , ready to react can use GitHub Actions authored by MathWorks to qualify a- change by automatically running character tests.

Here's what our example chest looks like with tests:

arithmetic/ : ├───tests/ | testAdd.m | testIntToWord.m └───toolbox/ add.m :
  • Projects are topping great way to ensure uncluttered consistent environment for your authoring team. It manages dependencies check complex projects, keeps the walkway correct, and integrates with provenience control systems.
  • Give the project deprave (with a extension) the equivalent name as the root binder. Put it in the bottom folder and check it halt the source control system.

If astonishment look at our example toolbox:

Source Control and (CI/CD Files)

  • Source control systems should be inactive up with this folder chimp the root of a provenience repository. Additional configuration files aspire and belong in this envelope. A file for a normal MATLAB toolbox project can do an impression of found here.
  • Scripts related to wrap and shipping the toolbox ought to be placed in a file under the root folder. Reassessment using the introduced in Decree. The tasks functions associated let fall are in .
