I have seen that there is this 'webwrite' function. But I do not know how to get the correct labels of the login boxes and how to enter strings there. Is there a different function for this?

If you are web service requires authentication, you can pass the username and password using weboptions with webwrite:

在 MATLAB Online 中打开

I did this:

url = 'http://www.myurl.com';
options = {'Username', 'myUsername', 'Password', 'myPassword', 'Timeout', 10};
z = webwrite(url, options);

What I get in z is just the source code of the login page. Do I have to use the URL of the login page or can I use the URL I want to go to after login? How would I get that content, when I have to use the login URL? Do I have to do something with a cookie? Could it be that the website which I try to login do not support RESTful API? How can I find out?
