In src/library/stats/src/distance.c Where else did you think the C source code for the stats package would be but src/library/stats/src? You will need to add your own function, and BTW, I don't think `the Bhattacharyya method' is appropriate for dist, as it is defined for distributions, not data items. It's even defined that way in your own paper http://www.speech.kth.se/ctt/publications/papers03/icphs03_giampi.pdf although you make Gaussian assumptions about the distributions whihc you did not in your posting. -- Brian D.
