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.
