function prob = gmmprob(mix, x)%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.%%	See also%	GMM, GMMPOST, GMMACTIV%%	Copyright (c) Ian T Nabney (1996-2001)% Check that inputs are consistenterrstring = consist(mix, 'gmm', x);if ~isempty(errstring)  error(errstring);end% Compute activationsa = gmmactiv(mix, x);% Form dot product with priorsprob = a * (mix.priors)';
