A tool to convert MATLAB code to Python


I have a bunch of MATLAB code from my MS thesis which I now want to convert to Python (using numpy/scipy and matplotlib) and distribute as open-source. I know the similarity between MATLAB and Python scientific libraries, and converting them manually will be not more than a fortnight (provided that I work towards it every day for some time). I was wondering if there was already any tool available which can do the conversion.

There are several tools for converting Matlab to Python code.

The only one that's seen recent activity (last commit from June 2018) is Small Matlab to Python compiler (also developed here: SMOP@chiselapp).

Other options include:

  • LiberMate: translate from Matlab to Python and SciPy (Requires Python 2, last update 4 years ago).
  • OMPC: Matlab to Python (a bit outdated).

Also, for those interested in an interface between the two languages and not conversion:

  • pymatlab: communicate from Python by sending data to the MATLAB workspace, operating on them with scripts and pulling back the resulting data.
  • Python-Matlab wormholes: both directions of interaction supported.
  • Python-Matlab bridge: use Matlab from within Python, offers matlab_magic for iPython, to execute normal matlab code from within ipython.
  • PyMat: Control Matlab session from Python.
  • pymat2: continuation of the seemingly abandoned PyMat.
  • mlabwrap, mlabwrap-purepy: make Matlab look like Python library (based on PyMat).
  • oct2py: run GNU Octave commands from within Python.
  • pymex: Embeds the Python Interpreter in Matlab, also on File Exchange.
  • matpy: Access MATLAB in various ways: create variables, access .mat files, direct interface to MATLAB engine (requires MATLAB be installed).
  • MatPy: Python package for numerical linear algebra and plotting with a MatLab-like interface.

Btw might be helpful to look here for other migration tips:

On a different note, though I'm not a fortran fan at all, for people who might find it useful there is:

There's OMPC, "Open-source Matlab-to-Python Compiler", mentioned by @IoannisFilippidis in his answer, -- haven't used it though.
