Convert MEXW64 to M

Understanding mexw64 and m file formats

mexw64 files are compiled binary files used by MATLAB on 64-bit Windows systems. These files are created from C, C++, or Fortran source code and serve as dynamically linked subroutines that can be called directly from MATLAB, offering high performance for computationally intensive tasks.

m files, on the other hand, are plain text scripts or function files written in the MATLAB programming language. They contain human-readable code and are the standard way to write and share MATLAB algorithms and functions.

Why convert mexw64 to m files?

Converting a mexw64 file to an m file is often desired when you want to understand, modify, or debug the underlying algorithm. However, this conversion is not straightforward because mexw64 files are compiled binaries, not source code. Direct conversion is generally not possible unless you have access to the original C/C++/Fortran source code used to create the MEX file.

Possible approaches to conversion

• Obtain the original source code: If you have access to the C/C++/Fortran source, you can manually rewrite or adapt the logic into an m file.
• Reverse engineering: Decompiling a mexw64 file is extremely difficult and often not feasible due to code optimization and loss of high-level structure during compilation.
• Contact the author: The best approach is to contact the developer of the MEX file and request the original source code or an m file equivalent.

Recommended software and tools

There is no direct software that can convert mexw64 binaries to m files. However, if you have the source code, you can use:

• MATLAB: Use File → New → Script to create a new m file and manually translate the logic from the source code.
• MATLAB Editor: For editing and testing m files.
• Text editors (e.g., Notepad++, VS Code): For writing and editing m files.

Summary

Direct conversion from mexw64 to m file is not possible due to the compiled nature of MEX files. The best solution is to obtain the original source code and manually rewrite it as an m file using MATLAB or a text editor.
