How to document a matlab project with multiple classes using sphinxcontrib-matlabdomain?

Question

I tried to document a large Matlab project using Sphinx and the sphinxcontrib-matlabdomain package. It works great for a single folder, in which all .m files are stored. However, my project contains several classes stored in separate folders, such as:

   project
    |-- matfiles
    |    |-- @class1
    |    |    |-- class1.m
    |    |    |-- method1.m
    |    |    |-- method2.m
    |    |    +-- method1.m
    |    |-- @class2
    |    |    |-- class2.m
    |    |    |-- methodA.m
    |    |    |-- methodB.m
    |    |    +-- methodC.m
    |    +-- function
    |         |-- fun1.m
    |         |-- fun2.m
    |         +-- fun3.m
    +-- doc
         |-- conf.py
         +-- index.rst

I add the following lines to conf.py:

matlab_src_dir = os.path.abspath('..')
extensions = [
    'sphinx.ext.autodoc',
    'sphinxcontrib.matlab',
]
primary_domain = 'mat'

And I added the following lines to index.rst:

.. module:: matfiles

.. automethod:: class1.method1

I got the following error:

Exception occurred:
  File "/Library/Python/2.7/site-packages/sphinxcontrib/mat_documenters.py", line 788, in import_object
    if self.object.attrs.get('Static'):

So my question is, is there a way to document Matlab class projects with multiple classes, where the class methods are stored in a folder named @class?
