Difficulty:
(5)
Rate
The input is the number of dimensions M and the parameter H.
The output is a point cloud W involving N points.
W is N uniformly distributed points with M dimensions on the unit hyperplane.
The relationship between M, H and point cloud size N is as follows.
In the case of M=3 dimensions, the results for cases where H is 1 to 6 are as follows.
Ex)
  • [W,N] = SLD(M=3,H=2) -> W = [0 0 1; 0 .5 .5; 0 1 0; .5 0 .5; .5 .5 0; 1 0 0]; N = 6;
  • [W,N] = SLD(M=5,H=2) -> W = [0 0 0 0 1; 0 0 0 .5 .5; 0 0 0 1 0; 0 0 .5 0 .5; 0 0 .5 .5 0; 0 0 1 0 0; 0 .5 0 0 .5; 0 .5 0 .5 0; 0 .5 .5 0 0; 0 1 0 0 0; .5 0 0 0 .5; .5 0 0 .5 0; .5 0 .5 0 0; .5 .5 0 0 0; 1 0 0 0 0]; N = 15;
