.mat File Extension

Developer: The MathWorks
File type: MATLAB MAT-File
You're here because you have a file that has a file extension ending in .mat. Files with the file extension .mat can only be launched by certain applications. It's possible that .mat files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .mat file?

Files with the .mat extension are files that are in the binary data container format that the MATLAB program uses. The extension was developed by Mathworks and MAT files are categorized as data files that include variables, functions, arrays and other information. MAT files can be saved in a variety of formats as long as users choose to save them in a version that belongs to the MATLAB Preferences. There are the so called level 4 MAT files wherein two-dimensional matrices and character strings are supported and there is also the level 5 MAT files wherein several things are included like the cell arrays, objects, multidimensional numeric arrays, structures and character arrays. MAT files are also useful when it comes to representing audio in various formats such as 16-bit signed integer, 8-bit unsigned integer and 64-bit floating point. Mathworks MATLAB is the software used to open MAT files. It is an application used to develop algorithm, visualize and analyze data as well as to compute numbers.

how to open a .mat file?

Launch a .mat file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .mat file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .mat files aren't yet associated with it. In this case, when you try to open a .mat file, you can tell Windows which application is the correct one for that file. From then on, opening a  .mat file will open the correct application.

The MathWorks MATLAB

The MathWorks MATLAB

The Mathworks MATLAB is a multi-faceted environment and fourth-generation programming language that's designed to perform complex numerical computations in academic and industrial research. It's widely used in Computer Science, Applied Mathematics, Economics, and Engineering. Mostly, MATLAB is used to implement algorithms, plot functions, chart data, and manipulate matrices. The integration of the MuPAD symbolic engine gives MATLAB users the capability to perform symbolic computations as well. In addition, the Simulink package allows graphical simulations across multiple platforms and uses model-based design when developing dynamic and embedded applications. MATLAB's interactive feature helps scientists and businesses in their collaborative research, iterative exploration, and creative problem solving. Its other key features include graphical tools for visualizing data and development tools for optimizing the code. MATLAB also interfaces smoothly with other languages, such as C and Java, and external applications like Excel or Access.

a word of warning

Be careful not to rename the extension on .mat files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .mat. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
