gives the rational polynomial function of x, with numerator order m and denominator order n, that interpolates the curve with x and y coordinates and generated as a function of t, at the interpolation points .

gives the rational interpolant with the interpolation points chosen automatically from the interval to .
  • The following options can be given:
