improved_gaborfilter
- Bi-dimensional Gabor filter with DC component compensation This version of the 2D Gabor filter is basically a bi-dimensional Gaussian function centered at origin (0,0) with variance S modulated by a complex sinusoid
Helmholtz
- A 2D homogeneous Helmholtz case (u=sin(x)cos(y) with a square) with ％ two Dirichlet edges (x=1,y=1) and two Neumann edges (x=0,y=0) ％ by indirect symmetric BKM
