How to call "MATLAB engine for Python" in Django?

Question

I have installed "MATLAB engine for Python" from MathWork. My python version is 3.4 and it works well if I put my own-written m.file together with .py file under the same folder.

But everything went wrong when I want to use that engine in Django. The .m function is called "doa.m". The structure of my project is like this: Project Structure

and my views.py is:

import os
....
from django.shortcuts import render
import matlab.engine
....
def result(request):
    eng = matlab.engine.start_matlab()
    eng.doa(nargout=0)
    return render(request, 'result.html')

and my urls.py is:

url( r'result/$', views.result, name='result'),

However, when I go into http://127.0.0.1:8000/result/, the error is: Undefined function or variable 'doa'. Trceback is:

Environment:


Request Method: GET
Request URL: http://127.0.0.1:8000/result/

Django Version: 1.9.2
Python Version: 3.4.4
Installed Applications:
['django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.sites',
 'django.contrib.messages',
 'django.contrib.staticfiles',

 'jfu']
Installed Middleware:

 'django.contrib.auth.middleware.AuthenticationMiddleware',
 'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
 'django.contrib.messages.middleware.MessageMiddleware',
 'django.middleware.clickjacking.XFrameOptionsMiddleware']



Traceback:

Can anyone explain it to me? Thanks!

Instead of your own file, could your try to call some built-in command? Maybe `eng.plus(1,2,nargout=1)`? Did you add your own m file to the search path in matlab? Looks like the engine is okay but matlab isn't finding your file. — Daniel, Feb 14 '16 at 12:29

For example, for Matlab 2015b, under "Home" Tab, click "set path", then click "add folder" and add the folder path where your Django project exists.
