A sixth order fast direct helmholtz equation solver

An O(h6) accurate difference approximation to solutions of the Helmholtz equation is derived. The discrete equations are solved using a reduction procedure and Fourier analysis. Its computational performance is compared with a fourth order similar method over a set of linear and mildly nonlinear elliptic boundary value problems.
