* HISTORY
* $Log: tmat.h,v $
* Revision 1.1.1.1 2006/05/23 18:45:03 dhuggins
* re-importation
*
* Revision 1.1 2005/09/29 21:51:19 dhuggins
* Add support for Sphinx3 tmat files. Amazingly enough, it Just Works
* (but it isn't terribly robust)
*
* Revision 1.9 2005/06/21 19:23:35 arthchan2003
* 1, Fixed doxygen documentation. 2, Added $ keyword.
*
* Revision 1.6 2005/06/13 04:02:56 archan
* Fixed most doxygen-style documentation under libs3decoder.
*
* Revision 1.5 2005/05/03 04:09:09 archan
* Implemented the heart of word copy search. For every ci-phone, every word end, a tree will be allocated to preserve its pathscore. This is different from 3.5 or below, only the best score for a particular ci-phone, regardless of the word-ends will be preserved at every frame. The graph propagation will not collect unused word tree at this point. srch_WST_propagate_wd_lv2 is also as the most stupid in the century. But well, after all, everything needs a start. I will then really get the results from the search and see how it looks.
*
* Revision 1.4 2005/04/21 23:50:26 archan
* Some more refactoring on the how reporting of structures inside kbcore_t is done, it is now 50% nice. Also added class-based LM test case into test-decode.sh.in. At this moment, everything in search mode 5 is already done. It is time to test the idea whether the search can really be used.
*
* Revision 1.3 2005/03/30 01:22:47 archan
* Fixed mistakes in last updates. Add
*
*
* 20.Apr.2001 RAH (rhoughton@mediasite.com, ricky.houghton@cs.cmu.edu)
* Added tmat_free to free allocated memory
*
* 29-Feb-2000 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
* Added tmat_chk_1skip(), and made tmat_chk_uppertri() public.
*
* 10-Dec-1999 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
* Added tmat_dump().
*
* 11-Mar-97 M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
* Started based on original S3 implementation.
