Hi,
I found a github repo regarding Quandl and how to access it with Python. Here is the github link: https://github.com/quandl/quandl-python
You can make use of MATLAB-Python interface to call python libraries and functions from MATLAB. You can learn about it on the link given below:
Here is an example MATLAB code for get 'AAPL' price history:
data = py.quandl.get_table('ZACKS/FC', ticker='AAPL')
disp(data)
Please note that you have to have MATLAB compatible Python version installed. To know more, check out: https://www.mathworks.com/support/requirements/python-compatibility.html
Hope it helps.
