Produces the sizes of the clusters in the hard clustering sense (objects are considered to be assigned to clusters only if the corresponding membership degree are >=0.5).

Usage

cl.size.H (U)

Arguments

`U`	Membership degree matrix

Value

clus.size

Vector containing the sizes of the clusters

Examples

n=20
k=3
## randomly generated membership degree matrix
U=matrix(runif(n*k,0,1), nrow=n, ncol=k)
U=U/apply(U,1,sum)
## cluster size in the hard clustering sense
clus.size=cl.size.H(U)
