摘要

Helmholtz equation is a special kind of elliptic partial differential equation. Solving Helmholtz equation is often needed in many scientific and engineering problems. The efficient approach to solving Helmholtz equation is through using Fast Fourier Transform (FFT). In practice, boundary conditions must be considered, and several discrete Fourier transforms such as Discrete Sine and Cosine Transf...
