I am a student who is getting used to Matlab.
I am trying to write a Matlab code that will goto yahoo finance, get the price of a specific stock and save it into a text file.
I am using urlread / urlwrite commands, but I have not been successful. Can anyone show me a sample script file or point me to a relevant link. Thanks in advance.

If you have datafeed toolbox, you may try the following code.
conn = yahoo('http://download.finance.yahoo.com');
Yahoo_HSI_Data = fetch(conn,{'^HSI'},{'Adj Close'},'2012-01-01','2012-04-01','d');
You will get Hang Seng Index daily Adjusted Close Data from 2010-01-01 to 2012-04-01 . The first col is Date. And the second col is Close Price .

To grab a single delayed quote (using Apple -- AAPL -- as an example here).
txt=urlread('http://download.finance.yahoo.com/d/quotes.csv', 'get', ...
{'s', 'AAPL', 'f', 'sl1d1t1c1ohgv', 'e', '.csv'} )
This return a line of text with around 10 comma-separated datum (timestamp, bid, ...). Honestly, I don't understand the magic string in the format ('f') passed to the server, but the command will fail if you omit it.
This may be enough for casual use, but serious users will want to look into MathWorks products like the Datafeed Toolbox.
