I am looking to create a classifier in Matlab, but I'm having some issues in understanding how exactly it works. I have several data sets of n x 9 arrays with readings from 3 separate 3-axis analog sensors (outputting values in m/s^2), and I want to create a classifier to distinguish between a state described by each of these arrays (walking, standing, running, etc.). I am having significant issue understanding how the classifier app in Matlab can train a model to do such a thing, however, and each time I attempt to "train" it, I get exceptionally poor model performance. I am obviously missing something key here, and I'm not sure where to go. I do have a fairly elementary understanding of classifiers, but I'm finding the documentation available to be confusing.

Are you talking about the training and classify()/predict() functions, or the Classification Learner app?
