**Course Title:** MATLAB Programming: Applications in Engineering, Data Science, and Simulation **Section Title:** Packaging, Deployment, and Version Control **Topic:** Package a MATLAB project and deploy it as a standalone application or share it as a toolbox.(Lab topic) **Objective:** In this lab, you will learn how to package a MATLAB project and deploy it as a standalone application or share it as a toolbox. You will use MATLAB's packaging and deployment tools to create a deployable application that can be shared with others. **Materials Needed:** * A MATLAB project you want to package and deploy (e.g., a GUI application, a script, or a toolbox) * MATLAB Release 2019b or later * MATLAB Compiler (included with MATLAB) * MATLAB Runtime (optional, but recommended for distributing standalone applications) **Key Concepts:** * Packaging MATLAB projects * Creating standalone applications * Deploying toolboxes * Using MATLAB Compiler and MATLAB Runtime **Step 1: Prepare Your Project** Before packaging your project, make sure you have the following: 1. A well-organized folder structure for your project 2. All necessary files (e.g., .m files, .mat files, images) 3. Any required third-party libraries or dependencies Review your project's content and structure to ensure it is self-contained and ready for packaging. **Step 2: Create a Toolbox** To create a toolbox, you need to package your project into a single folder with the following structure: ``` +mytoolbox |-+toolbox | |-+translations | | |- default.po | | |- locale.po (optional) | |-math_functions | |- utilities | |- toolbox.m |-README.md |- Changelog.md ``` This structure includes: * `+mytoolbox`: The root folder for your toolbox * `+toolbox`: A subfolder containing your toolbox files * `translations`: A subfolder for storing translation files * `math_functions`, `utilities`, etc.: Subfolders for your toolbox functions and utilities * `toolbox.m`: A file that defines your toolbox's name, version, and dependencies * `README.md` and `Changelog.md`: Files for describing your toolbox and tracking changes To create a toolbox, you can use the ` matlab.addons.toolbox` function. Here's an example: ```matlab %% Create a toolbox folder toolbox_folder = '+mytoolbox'; %% Add toolbox files and folders matlab.addons.toolbox ... ('ToolboxName', 'My Toolbox', ... 'ToolboxVersion', '1.0', ... 'ToolboxDescription', 'My Toolbox Description', ... 'ToolboxIcon', [], ... 'ToolboxLicense', [], ... 'ToolboxURL', [], ... 'ToolboxFileNames', {'+mytoolbox/toolbox.m'}); %% Save the toolbox matlab.addons.toolbox('ToolboxSave', true); ``` **Step 3: Compile and Package Your Project** To deploy your project as a standalone application or toolbox, you need to use the MATLAB Compiler. Here's an example: ```matlab %% Compile the project project = {[pwd ','filesep,'myGUI.m']}; compile_command = {[project],'-nodisplay', ... '-nojvm', ... '-a','mylib.lib', ... '-W', 'compopt', '-a', ... 'my_app.prj'}; compile_command = sprintf('%s %s', 'mcc', compile_command{:}); system(compile_command); ``` This code compiles the `myGUI.m` file and creates a standalone application. **Step 4: Create a Standalone Application** To create a standalone application, you need to create a `.prj` file that defines the application's settings. Here's an example: ```matlab %% Create a project file project = {[pwd filesep 'my_app.prj']}; %% Define the application settings options = {'-nodisplay', ... '-nojvm', ... '-a', 'mylib.lib', ... '-W', 'compopt', '-a'}; options = sprintf('%s %s', options{:}); %% Save the project file fid = fopen(project{:}, 'w'); fprintf(fid, 'version 8.7\n'); fprintf(fid, 'type = application\n'); fprintf(fid, 'requirelib = ""\n'); fprintf(fid, 'filename = "my_app.exe"\n'); fprintf(fid, 'output = ""\n'); fprintf(fid, 'title = "My Application"\n'); fprintf(fid, 'icon = ""\n'); fprintf(fid, 'version = "1.0"\n'); fprintf(fid, 'author = "Your Name"\n'); fprintf(fid, 'toolchain = ""\n'); fclose(fid); ``` **Step 5: Deploy Your Application** To deploy your standalone application, you can use the ` mcc` command. Here's an example: ```matlab %% Deploy the application project = {[pwd filesep 'my_app.prj']}; deploy_command = {[project],'-nodisplay', ... '-nojvm', ... '-a','mylib.lib', ... '-W', 'compopt', '-a'}; deploy_command = sprintf('%s %s', 'mcc', deploy_command{:}); system(deploy_command); ``` **Troubleshooting:** * If you encounter issues with the compilation or deployment process, review the MATLAB Compiler documentation and the ` mcc` command documentation for more information. * Make sure you have the necessary dependencies and libraries installed on your system. **Conclusion:** In this lab, you learned how to package a MATLAB project and deploy it as a standalone application or share it as a toolbox. You used MATLAB's packaging and deployment tools to create a deployable application that can be shared with others. **Additional Resources:** * MATLAB Compiler Documentation: [www.mathworks.com/help/compiler/index.html](http://www.mathworks.com/help/compiler/index.html) * MATLAB Runtime Documentation: [www.mathworks.com/help/compiler/deploying-to-standalone-targets.html](http://www.mathworks.com/help/compiler/deploying-to-standalone-targets.html) * MATLAB Add-Ons Documentation: [www.mathworks.com/help/matlab/add-ons/index.html](http://www.mathworks.com/help/matlab/add-ons/index.html) **Questions or Comments?** If you have any questions or need help with this lab, please leave a comment below.
