MATLAB (Matrix Laboratory) is a high-level programming language and interactive environment widely used for numerical computation, visualization, and programming. Executing MATLAB code efficiently is crucial for maximizing productivity and achieving accurate results. This guide will walk you through the various methods for running MATLAB code, from simple commands to complex scripts and functions.

Running Simple Commands
MATLAB's Command Window allows you to execute individual commands interactively. This is ideal for quick calculations, testing code snippets, or running commands during debugging.

To run a command, simply type it into the Command Window and press Enter. For example:

This code will display the result of c, which is 15, in the Command Window.

Executing Scripts
Scripts are files containing a sequence of MATLAB commands. They are useful for automating repetitive tasks and organizing code. Scripts have a .m extension.

To create and run a script:

Open the MATLAB editor by clicking on "New Script" or using the shortcut Ctrl+N.

Write your code in the editor. For example:

Save the script with a .m extension, such as add_numbers.m.

Run the script by typing the script name (without the .m extension) in the Command Window and pressing Enter:

Using Functions
Functions are similar to scripts but are more versatile and powerful. They accept input arguments and can return outputs. Functions are defined in separate files, each named after the function, with a .m extension.

To create and use a function:

Open the MATLAB editor and write your function. For example:

Save the file with the same name as the function, e.g., add_numbers_function.m.

Call the function from the Command Window or another script:

Running Scripts and Functions from the Command Line
MATLAB scripts and functions can also be executed from the command line (outside the MATLAB environment). This is useful for batch processing or integrating MATLAB with other software.

To run a script or function from the command line:

Open your command prompt or terminal.

Navigate to the directory containing your MATLAB script or function.

Use the following syntax to run MATLAB in non-interactive mode:

Advanced Execution Techniques
MATLAB offers several advanced methods for running code, including:

Live Scripts: Interactive scripts that combine code, output, and formatted text in a single document. Useful for creating reports and teaching materials.

MATLAB Compiler: Converts MATLAB code into standalone applications or software components.

Parallel Computing: Execute code on multiple processors to speed up computations, using tools like parfor and spmd.

Conclusion
Executing MATLAB code can be as simple as running individual commands in the Command Window or as complex as deploying applications using the MATLAB Compiler. Understanding the various methods available for running MATLAB code will help you choose the best approach for your specific needs and enhance your productivity in MATLAB.
