Programme for Discrete Gaussian Distribution

Discrete Gaussian Distribution (D_{Lambda,r}):

Condition:

1. Lattic (Lambda)
2. Scaling factor (r)
3. Central Point ({f c}={f 0})

Matlab implement:

x=-25:25;
y=-25:25;
[xx,yy]=meshgrid(x,y);
z=sqrt((xx).^2+(yy).2);
z=gaussmf(z,[rsqrt(2) 0]);
stem3(x,y,z,'--*');

r=1

r=0.5
