Subject: problem about 'urlread'

Message: 1 of 2


I tried to get data from url 'http://trend.lecai.com/bjkl8Zst!bjkl8jbzs.jhtml?date=2013-03-20'.

Access to the webpage works fine in firefox, but when I run in matlab

s=urlread('http://trend.lecai.com/bjkl8Zst!bjkl8jbzs.jhtml?date=2013-03-20');

The returned 's' is incorrect. Any solution?

s =

Looks like an internal server error of the website, probably because it did not expect the default UserAgent used by urlread.
