PadeApproximant

PadeApproximant[expr, {x, x0, {m, n}}]
gives the Padé approximant to expr about the point x=x0, with numerator order m and denominator order n.
PadeApproximant[expr, {x, x0, n}]
gives the diagonal Padé approximant to expr about the point x=x0 of order n.
  • Mathematica can find the Padé approximant about the point x=x0 only when it can evaluate power series at that point.
