I'm guessing it's just supposed to be butter, there's no function in MATLAB called 1butter, and there couldn't be because numbers can't be at the beginning of a function name, and I doubt it's lbutter (i.e. a lowercase L), and the function signature/usage looks just like butter. I think it's a typo.
