Hello,

One solution I can think of would be to write an interface to the

Matlab command prompt using pexpect, the python implementation of

expect. Expect allows you to spawn and interact with other process.

There is already a cool implementation of exactly this in Sage, an

open source computer algebra system written in python.

If you want to see something work immediately, try installing sage

(sage.math.washington.edu/sage).

I did some experimenting (in a linux environment) and it works quite

nicely.

Here is an example:

I wrote a simple matlab function myAdd saved as myAdd.m

function thesum = myAdd(a, b)

thesum = a+b;

I put the file in my Matlab search path.

In sage, I did this:

sage: a = matlab('myAdd(2,2)')

sage: a

4

This would require you to run your python scripts using Sage instead

of just python.

You can import the sage library into python, but it's kind of non-

trivial.

At the very least, you can study sage's matlab interface, which is

written in python. It is very easy to spawn process and give commands

with pexpect, but not as fun to get results because it involves

parsing to get the output.

Good luck,

-Dorian

Hi,

I am implementing a small Python project, what I am going to do is to

open Matlab and run some M-files, and get some output from Matlab

command prompt.

I have no idea how to open Matlab from Python!

Any suggestions would be appriciated!
