MATLAB data
File type: Various data file
A .mexa64 file is a compiled MATLAB MEX file for 64-bit Linux systems. It contains executable code and data that MATLAB can load and run as a function.
The file belongs to MATLAB, MathWorks' numerical computing software and programming language.

The .mexa64 file extension identifies a MATLAB MEX binary compiled for 64-bit Linux. MEX files extend MATLAB by allowing it to call compiled code written in languages such as C, C++, or Fortran.
A .mexa64 file contains compiled code and data used by MATLAB for Linux. It is not normally intended to be opened independently. MATLAB loads it as an executable function when the file is available on the MATLAB path or in the relevant working directory.
MATLAB is available for Windows, macOS, and Linux, but this particular file type is intended for the 64-bit Linux version. A MEX file must match the operating system and supported MATLAB environment in which it is used.
Open the .mexa64 file in MATLAB on a 64-bit Linux system. Add the file's folder to the MATLAB path or make it the current working directory, then call the MEX function by its function name. It is not normally opened as a document or run as a standalone application.
If MATLAB cannot load the file, it may have been compiled for a different platform or may require dependencies that are not installed.
A .mexa64 file is compiled executable code, so it generally cannot be meaningfully converted to another data format. To produce a MEX file for another platform, obtain the original C, C++, or Fortran source code and compile it with MATLAB's MEX build tools for that platform.
