This is a little script which was designed for educational purposes. It runs out of the box and generates a random data set of 2D Gaussian mixtures and visualizes the inference process with an infinite Gaussian mixture model.

I fixed that issue by setting negative values as 0: gammaln(max(x,0))

I hope it doesn't break it

something wrong with the gammaln function, the variable should be positive. a nice matlab script.
