Guys, I've got about half an hour to work on kmath before the new year. And started to look into functions and interpolation. I already have a phylosophical question: what is a Polynom. Basically we expect it to be a function, but kmath logic wants it to be a real vector without argument type which becomes function when used inside an algebra context of specific type. It makes sense from mathematical point of view, but from experience with other math libraries, it is a little bit wierd. Any opinions?
