Function File: vpe = partition_entropy (soft_partition, a)

Return the partition entropy for a given soft partition.

The arguments to partition_entropy are:

• soft_partition - the membership degree of each input data point in each cluster
• a - the log base to use in the calculation; must be a real number a > 1

The return value is:

• vpe - the partition entropy for the given soft partition
