Sources of MAT Problems

Frequent MAT Opening Issues

The MathWorks MATLAB is Not Installed

You encounter an error message such as "- Can't Open MAT Files" when trying to open your MAT. When this happens, it is commonly due to The MathWorks MATLAB missing in - . Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

Tip: If you have another software that you know opens MAT files, you can select it by hitting the "Show Apps" button.

The MathWorks MATLAB Requires Update

Sometimes your installed version of The MathWorks MATLAB won't support your MATLAB MAT-File file. Download the latest The MathWorks MATLAB version from the MathWorks website to ensure you have the correct one installed. Most of the time your MATLAB MAT-File file was created by a newer The MathWorks MATLAB than what you have installed.

Tip: If you right-click on your MAT file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Summary: In either case, the majority of problems opening MAT files are related to not having the correct software application installed on your computer.

• File corruption affecting your MAT file
• The MAT is infected with a virus
• Drivers associated with MAT software need to be updated
