I am using MATLAB 2016B.
I have a webpage which I want to download the data from.
url = 'https://openfigi.com/search#!?search=CUSTOM&pageSize=100&page=1&filters=EXCH_CODE:..cme&simpleSearchString=S%26P500%20EMINI%20OPTN';
data = webread(url);
When i run this I get:
Error using webread (line 116)
Too many input arguments.
When I try
data = urlread(url);
The function clearly works as it's supposed to, however the response does not contain the data of interest.
Please can someone help me return the table data using matlab. thanks

What you have for webread works fine for me in R2016b, Win7x64.
My guess is you're shadowing one of the functions that webread is calling.

Thanks Sean.
I dont think thats the case. This is a fresh install of matlab on a new PC. How can I check to be sure?
When I try again with the same website and the BBC website, I get an error for the first and no error for the BBC one.
Can you copy the output from your successful call here please?
