How to Write a Function and Call It in MATLAB

Writing Functions in MATLAB:

Functions are a fundamental part of MATLAB programming, allowing you to break down your code into smaller, manageable pieces. Here’s how you can create a function in MATLAB:

  1. Start by opening the MATLAB Editor.
  2. Click on ‘New Script’ to create a new script file.
  3. Write your function code in the script file. Make sure to use the function keyword followed by the function name and input arguments.
  4. Save the script file with a .m extension. The file name should match the function name.
  5. Now you have successfully created a function in MATLAB.

Calling Functions in MATLAB:

Once you have defined a function, you can call it from other scripts or the command window. Here’s how you can call a function in MATLAB:

  1. In the command window, type the function name followed by the input arguments in parentheses.
  2. Press Enter to execute the function.
  3. The function will run, and you will see the output in the command window.
  4. You can also call the function from another script by using the function name with input arguments.

By writing functions in MATLAB, you can improve the modularity and reusability of your code. This makes it easier to maintain and debug your programs. Start incorporating functions into your MATLAB projects today to streamline your coding workflow.
