I got one problem , that with urlwrite function,can it work for http authentication also? I have checked early some people said: function has a "params" argument, but these are CGI-style parameters that get encoded in the URL. Authentication is done with lower-level HTTP Request parameters.
Here I found that Authentication option in urlwrite.m is ONLY available since Matlab release 2013a. You can check your matlab version by typing ver at the Matlab prompt. With the example
URL = '';
fileName = tempname;
gzFileName = [fileName '.gz'];
[gzFileName,st] = urlwrite(URL,gzFileName, 'Authentication', 'Basic', ...
'Get', {'Username', '<username>', 'password', '<password>', ...
'2011-11-10T18:00:00Z', 'END_DATE', '2011-11-10T21:00:00Z', ...
'NON_BROWSER', '1'});
fileNames = untar(fileName);
for iFile = 1:numel(fileNames)
this gives me error all the time. Is this correct parameters?

I don't think it's possible using urlwrite, but the weboptions of the newish websave allows you to specify username / password.

Just seen your edit to the question. The syntax of your urlwrite call is wrong. It should be
[gzFileName,st] = urlwrite(URL,gzFileName, 'Authentication', 'Basic', ...
'Username', '<username>', 'password', '<password>', ...
'2011-11-10T18:00:00Z', 'END_DATE', '2011-11-10T21:00:00Z', ...
'NON_BROWSER', '1'});
The reply I get (without the username / password)
which is expected since I didn't supply the username/password
This won't solve the problem that you can't connect to anything at all, though.

You hit the spot. The settings in my preference/Web is wrong, it was using Proxy server..Now after I took it away, it works with this.
What is the Get parameter, also the time etc. I want to download the file which is linked in the url ... This might be the problem? I do not think I need start date and end data etc...
[gzFileName,st] = urlwrite(url,wanted_h5, 'Authentication', 'Basic', ...
'Username', '<uuuu>', 'password', '<ooo>');
But when I tried this it did not download also.
Thanks a lot , I will try to figure it out

I have been using the URLREAD/WRITE_AUTH provided here, or similar, for years now.

In fact I am also using this function you mentioned. But I want to know is it possible when you login once you want to download many files, but only with one time the username and password is in memeory...that is why I am thinking if Matlab have the already working function would be nice. Because I do not know how to handle with this ...How do you handle with this? Thanks
