How do I interact with MATLAB from Python?

Question

A friend asked me about creating a small web interface that accepts some inputs, sends them to MATLAB for number crunching and outputs the results. I\'m a Python/Django deve

Answer 1

As an alternative, since Matlab R2014b, a Python library is provided to call Matlab from Python using the MATLAB Engine API for Python.

Answer 2

Regarding OS compatibility, if you use the matlab version for Linux, the scripts written in windows should work without any changes. If possible, you may also consider the possibility of doing everything with python. Scipy/numpy with Matplotlib provide a complete Matlab replacement.

Answer 3

There is a python-matlab bridge which is unique in the sense that Matlab runs in the background as a server so you don't have the startup cost each time you call a Matlab function.

it's as easy as downloading and the following code:

from pymatbridge import Matlab
mlab = Matlab(matlab='/Applications/MATLAB_R2011a.app/bin/matlab')
mlab.start()
res = mlab.run('path/to/yourfunc.m', {'arg1': 3, 'arg2': 5})
print res['result']

where the contents of yourfunc.m would be something like this:

%% MATLAB
function lol = yourfunc(args)
    arg1 = args.arg1;
    arg2 = args.arg2;
    lol = arg1 + arg2;
end

Answer 4

Take a look at mlabwrap which allows you to call Matlab via a python API
