**Course Title:** MATLAB Programming: Applications in Engineering, Data Science, and Simulation **Section Title:** Application Development with MATLAB **Topic:** Packaging and deploying standalone MATLAB applications **Objective:** By the end of this topic, you will be able to package and deploy standalone MATLAB applications using MATLAB's App Designer and Compiler. **Introduction** ---------------- In the previous topics, we explored how to build interactive applications using App Designer. However, these applications can only be run from within MATLAB. To share our applications with others who may not have MATLAB installed, we need to package and deploy them as standalone applications. In this topic, we will cover the process of packaging and deploying standalone MATLAB applications using App Designer and Compiler. **Prerequisites** ----------------- Before proceeding, ensure that you have: * MATLAB R2020a or later installed * App Designer installed * MATLAB Compiler installed (optional) **Packaging a MATLAB Application** ---------------------------------- To package a MATLAB application, follow these steps: 1. Open App Designer and create a new project or open an existing one. 2. Design and build your application as desired. 3. Go to the "Code View" tab and click on "Package" in the top toolbar or press "Ctrl+P" (Windows) or "Cmd+P" (Mac). 4. Select the packaging options: * Package as a standalone application * Package with MATLAB Runtime (if the application requires MATLAB to run) * Package with additional resources (e.g., images, audio files) **Deploying a Standalone Application** ------------------------------------- To deploy a standalone application, you can use the MATLAB Compiler. Here's how: 1. Open the MATLAB Compiler by typing ` mcc` in the Command Window. 2. Select the project you want to compile. 3. Choose the deployment options: * Compiler: Select the desired compiler (e.g., C, C++, Java) * Output Folder: Specify the folder where the compiled application will be saved * Architecture: Choose the target architecture (e.g., 32-bit, 64-bit) **Example: Packaging and Deploying a Simple Calculator App** --------------------------------------------------------- Let's package and deploy a simple calculator app using App Designer and Compiler. 1. Create a new project in App Designer and design a simple calculator interface with buttons for addition, subtraction, multiplication, and division. 2. Write code to handle the button clicks and perform the calculations. 3. Package the application as a standalone application using App Designer. 4. Compile the project using MATLAB Compiler. **View compiled code:** [https://www.mathworks.com/help/compiler/ug/mcc-function.html](https://www.mathworks.com/help/compiler/ug/mcc-function.html) **Key Concepts and Takeaways** --------------------------- * App Designer allows you to package MATLAB applications as standalone applications. * MATLAB Compiler is used to compile and deploy standalone applications. * Packaging options include packaging with MATLAB Runtime and additional resources. * Deployment options include choosing the compiler, output folder, and target architecture. **Common Issues and Solutions** ----------------------------- * **Error: Unable to package application**: Ensure that the project is built correctly and there are no errors in the code. * **Error: Unable to compile application**: Check the MATLAB Compiler settings and ensure that the correct compiler is selected. **Additional Resources** ---------------------- * MATLAB App Designer Documentation: <https://www.mathworks.com/help/matlab/app-designer.html> * MATLAB Compiler Documentation: <https://www.mathworks.com/help/compiler/index.html> * MATLAB Compiler Options: [https://www.mathworks.com/help/compiler/ug/available-mcc-options.html](https://www.mathworks.com/help/compiler/ug/available-mcc-options.html) **What's Next?** -------------- In the next topic, we will introduce you to machine learning and MATLAB's Machine Learning Toolbox. Please provide your feedback or ask for help if you have any questions or need further clarification on this topic. Your input is valuable for our continuous improvement.
