MATLAB wrapper for Python

MATLAB wrapper for Python

Description

matlab_wrapper allows you to use MATLAB in an convenient way from your Python scripts. The MATLAB session is started in the background and appears as a regular Python module.

matlab_wrapper uses standard MATLAB engine library and talks directly to the binaries through ctypes. You do not need to compile anything!

Usage

Initialize:

import matlab_wrapper
matlab = matlab_wrapper.MatlabSession()

Low level:

matlab.put('a', 12.3)
matlab.eval('b = a * 2')
b = matlab.get('b')

Workspace:

s = matlab.workspace.sin([0.1, 0.2, 0.3])

matlab.workspace.a = 12.3
b = matlab.workspace.b

Requirements

• Python (2.7)

• Matlab (tested with 2013b)

• Numpy (1.8)

Installation

pip install matlab_wrapper

Limitations

• Struct arrays are not yet supported.

• Support on Windows and OSX is not as good as on GNU/Linux (I’m looking forward to contributors).

Issues and Bugs

Alternatives

• pymatlab

  • pure Python, no compilation, using ctypes (good)

  • quite raw (ugly)

  • memory leaks (bad)

• mlabwrap

  • cool interface, mlab.sin() (good)

  • needs compilation (bad)

  • not much development (bad)

• mlab

  • similar interface to mlabwrap (good)

  • using raw pipes (hmm)

  • there is another very old package with the same name (ugly)

• pymatbridge

  • actively developed (good)

  • client-server architecture with ZeroMQ and JSON, complex (ugly)

  • missing basic functions, either get or put (bad)

  • nice ipython notebook support (good)
