Sorry, somehow I didn't send the full comment. This is great tool and I looked for such functionality in MATLAB. One issue is that it searching for the icon in current directory. It better to store it together with the function. Use fileparts(which(mfilename)) instead of pwd.
Nice thing. Too bad the Matlab web browser doesn´t have the same functionality as other browsers though... I could not even load the page that I am most interested in importing. Then again, I could ofcourse save this page as HTML using Firefox, Safari or Explorer and then use your tool to import it into Matlab, which is nice since I don´t have to open up Excel.
