 lyngby_km_within     - K-means within-variance (within intertia)

	function W = lyngby_km_within(X, Centers, assign, ...
           'PropertyName', 'PropertyValue')

       Input:    X         Datamatrix, size: examples x
                           variables. ie. if voxels are to be clustered
                           the datamatrix should be voxels x time.
                 Centers   Cluster center matrix
                 assign    Assignment vector
	
       Property: Type      [ {trace} | det | matrix ]

 	Output:	  within    The within variance	

       This function calculates the within cluster variance, ie., the
       within within inertia.
