A highly accurate and effective scheme for solving the time-dependent Schrodinger equation is implemented using Mathematica. The present code achieves a precision of one part in 1017, which is found to be independent of time steps. With a new wavefunction splitting algorithm and a more efficient method for evaluating transmission coefficients, the improved code requires considerably less CPU time than that reported in our previous publication.
