Try using GUIDE. Place a push button on the GUI, then right click and view the callback. It will make a function in the m-file where you can paste the code you gave.

Huh? How will the callback function for your button clash (conflict, interfere) with some other function you have called pushbutton1? Like I said, place a button there on the GUI and call it (set the "tag" property) to something like btnLoadDatabase. Then right click and say Callbacks->View Callback. You will get a function in the m-file called btnLoadDatabase_Click(). In that function paste the code you gave above for your load_database1 function (not including the function line itself of course).
