+%GMMPROB Computes the data probability for a Gaussian mixture model.
+%
+%	Description
+%	 This function computes the unconditional data density P(X) for a
+%	Gaussian mixture model.  The data structure MIX defines the mixture
+%	model, while the matrix X contains the data vectors.  Each row of X
+%	represents a single vector.
