wolffd@0: function e = dempot(x, mix)
wolffd@0: %DEMPOT	Computes the negative log likelihood for a mixture model.

wolffd@0: %	Description
wolffd@0: %	This function computes the negative log of the unconditional data
wolffd@0: %	density P(X) for a Gaussian mixture model.  The data structure MIX
wolffd@0: %	defines the mixture model, while the matrix X contains the data
wolffd@0: %	vectors.
