, <>= , . , @? / ! 1 3A , is a useful and popular tool for the approximation of sufficiently regular univariate functions. In fact, its partial sums provide an asymptotically optimal polynomial approximation, which can be constructed in a very efficient way by resorting to the FFT algorithm; see, e.g., the classical book [11], and e.g. the various… CONTINUE READING
