Well, it's just a little more complex: maxima does only the part of solving 
function, but the algorithm for best fit is implemented into Kartesio, and 
can't be done with maxima commands. Plus, the interface of Kartesio has been 
designed for this particular use, while Cantor is fundamentally a paper for 
mathematical calculations. It could be a good idea to write a plugin for 
that works with Kartesio as a backend, but I should think about how this 
be done.
