How to Create MAT file in MATLAB? [Save and Run]

MATLAB Programming Feature image

Today, I am writing this tutorial for creating and saving M-file in MATLAB. While learning MATLAB, you should know “How to create MAT file in MATLAB?”.

Why do you need a MAT-file?

If you are writing the program for solving technical computing or running Simulink model, you need to save the program as M-file in MATLAB.

What is an extension of MATLAB file?

In MATLAB, the new M-file will be saved with an extension of “m”. And MATLAB Simulink model will be saved with an extension of “mdl” or “slx

Note: M-file is a short abbreviation of MATLAB-file. It is also called as MAT-file. Sometimes, M-file is called as the “Script file”.

How to Create MAT file in MATLAB?

Here are the following steps, you should follow for creating a new file.

  • Firstly, open the MATLAB software. And click on the New Script topmost option from the Home of the MATLAB window. This new script is used for creating a new File in MATLAB. [as shown in below image]

  • After selecting the new script, you will see the Editor option. You will see the Untitled new M-File for writing the new MATLAB program.

  • Before writing any program or any technical computing in Command Window, you should Save the file in your desired folder.

Note: Extension of the new MATLAB file should be “mat” or ” m “ file.

MAT File Example:

For Example, Here I am saving the M-File with the naming DipsLab.m.

Sample MAT File Program (Example)

Write a MATLAB program to solve the mathematical calculation, for example, the addition of two numbers (calculate the value of ‘a’).


Let consider,

>> x=2; y=4;

>>  a=x+y

a     =



I am clicking on the Save Workspace option in the MATLAB window.  And saving this file with the name of the “Addition.mat” in the new folder.

You can write more MATLAB programs using Mathematical functions.
