Download data from a website

I need to download data from a website. Manually, I would enter a username and password and press a 'download' button and it would download into a csv file. Is it possible to do this in Matlab? I understand that I can use functions to read directly from a website but can't find much on the extra step of having to click on a button?

Rachel - when you press the button, what is the URL that is created to grab the data?

[Rachel]

It comes up with \data.html but it comes up with the same page in a browser and in Matlab using webread it comes up with just characters - e.g. (_ _)( \/ )( ) ( \ ( )(_ _)( ) ( )( \( )(_ _)( _)( ,) thanks

What parameters are you passing into webread?

[Rachel]

At the moment, just username and password. I'm not sure of the other options at the moment.
