    Backward differential formulae (BDF) are the basis of the highly efficient schemes for the numerical solution of stiff ordinary differen- tial equations for decades. An alternative multistep schemes (RBDF) based on barycentric rational interpolation is proposed. Specifically, robust new methods of orders 1 to 5 are derived. The local trun- cation error is analyzed for variable stepsizes in order to implement a variable order, variable stepsize prototype in Matlab. Aspects of the implementation are addressed in detail. Numerical experiments illustrate that the RBDF code compares well with Matlab’s ode15s.
