An accurate eighth order exponentially-fitted method for the efficient solution of the Schrödinger equation. (English) Zbl 0976.65060
This paper constructs an eighth-order exponentially fitted method for solving differential equations arising from the Schrödinger equation. A comprehensive order and truncation error analysis is given using MAPLE. A variable stepsize implementation is introduced and compared with existant methods on some simple problems.
