Daniel@0: %	Description
Daniel@0: %	NET = KNN(NIN, NOUT, K, TR_IN, TR_TARGETS) creates a KNN model NET
Daniel@0: %	with input dimension NIN, output dimension NOUT and K neighbours.
Daniel@0: %	The training data is also stored in the data structure and the
Daniel@0: %	targets are assumed to be using a 1-of-N coding.
Daniel@0: %
Daniel@0: %	The fields in NET are
Daniel@0: %	  type = 'knn'
Daniel@0: %	  nin = number of inputs
Daniel@0: %	  nout = number of outputs
Daniel@0: %	  tr_in = training input data
Daniel@0: %	  tr_targets = training target data
