hello everyone,
 I am trying to classify some 3D points ( the way i obtain them is
irrelevant here) into 4 categories, using the Neural Network
Toolbox...I have the 4 training set of points, one set for each
category and i would like matlab to be able to associate each point
from a test set to a category. how do i define an output to the
network in concordance to the input values. which aproach to this
problem do you think is best suited here?  
 Regards, A.U.
