protected PointData.Discrete()

PointData.Discrete

public PointData.Discrete(int n)

Make a PointData.Discrete with N points.

Parameters:

n - The number of points in the discrete set.

Method Detail

distance

public double distance(int p1,
              int p2)

Distance between 2 points.

Specified by:

distance in class PointData

Parameters:

p1 - index of the first point

p2 - index of the second point

Returns:

distance between the two points.

count

public int count()

The number of points in this data set.

Indexing begins from 1, not 0, which means that the points go from 1 to count(), inclusive. It is acceptable for an implementation to allow points to be added.

Specified by:

count in class PointData

Returns:

The number of points in the data set.

DSphere

public static SimplexStream DSphere(int d)

Make an instance of the boundary of the canonical (D+1)-Simplex.

Parameters:

d - The dimension of the "sphere-like" simplicial complex.

DSphereKskeleton

public static SimplexStream DSphereKskeleton(int d,
                             int k)
