.mexds files contain compiled code that MATLAB can load and call as a subroutine. They are used to extend MATLAB, a numerical computing software and programming language from MathWorks, with functionality implemented outside the MATLAB language.
The file is a platform-dependent binary rather than a document intended for direct reading. MATLAB must support the file's platform and binary format; a compatible MATLAB installation loads it when the corresponding function is called.
Open a .mexds file with a compatible installation of MATLAB from MathWorks. It is normally used from within MATLAB by placing it on the MATLAB path and calling the associated function, rather than opening it as a standalone document.
A .mexds file cannot normally be converted to a standard document or data format because it contains compiled code. If the original source code is available, it can be rebuilt with MATLAB's MEX tools for the required platform and MATLAB version.
