I am trying to use Matlab to grab some data from a website and have hit a dead end. When looking at the 'view source' in my web browser, I can see the data clearly. However, when I utilize the built-in Matlab function 'urlread' it only seems to retrieve the static portions of the webpage.
I'm assuming the webpage uses java and dynamically updates? Is there a way to have Matlab create a static image of the webpage to permit data gathering? Is there a better way? If so, would you please provide examples.
So frustrating 'view source' shows the data right there ... Thanks!

See the question marks (?) next Composite Rating for example. When I am logged in via my web browser, I see values (I have an account.) However, when I try to retrieve via urlread it shows the question marks. Is there a way to log in via Matlab before using urlread?

Use webread with a weboptions object containing your username and password:
webread('http://research.investors.com/quotes/nasdaq-apple-inc-aapl.htm', weboptions('Username', 'xxx', 'Password', 'yyy'))

To get more visibility to your question, you would be better off starting a new question of your own rather than highjacking somebody's else.
Please do so.
