RationalInterpolation
RationalInterpolation[expr,{x,m,n},{x1,x2,…,xn+m+1}]
gives the rational interpolant to expr with numerator order m and denominator order n, where x1,x2,… are the abscissas of the interpolation points.
RationalInterpolation[expr,{x,m,n},{x,x0,x1}]
gives the rational interpolant with the interpolation points chosen automatically on the interval x0 to x1.
