The Complete SPRLIB & ANNLIB

`double`	*`x`**	A `vector` of size `[0..ninput+1]` containing the current pattern to be clustered.
`double`	*`ed`**	A `vector` of size `[0..ninput+1]` containing the Euclidean distance of the current pattern to the cluster centers.
`double`	`b`**	A `matrix` of size `[0..ninput+1][0..ninattr+1]` containing the current cluster centers.
`double`	`pattern`**	A `matrix` of size `[0..ninput+1][1..ninattr+1]` containing the samples to be clustered.
`double`	`cluster_tbl`**	A `matrix` of size `[0..ninput+1][1..ninattr+1]` containing the description of a cluster, for each cluster the number of clustered samples and the sample numbers is maintained.
`int`	`ninput`	The number of samples.
`int`	`ninattr`	The number of features.
`int`	`active_nodes`	The number of clusters so far.
`double`	`threshold`	A threshold to decide whether a new cluster should be created.

The local variable used when calling the Pao clustering functions.
