摘要：
A new variable-step method is developed for the numerical integration of special second-order initial value problems. An application to the one-dimensional Schrodinger equation on the phase-shift problem, indicates that this new method is generally more accurate than other previously developed finite difference methods, especially in the case of high energies.
