Transition matrix data structure.
Definition: tmat.h:55
int16 n_state
Number source states in matrix (only the emitting states); Number destination states = n_state+1,...
Definition: tmat.h:59
uint8 *** tp
The transition matrices; kept in the same scale as acoustic scores; tp[tmatid][from-state][to-state].
Definition: tmat.h:56
int16 n_tmat
Number matrices.
Definition: tmat.h:58
tmat_t * tmat_init(char const *tmatfile, logmath_t *lmath, float64 tpfloor, int32 breport)
Initialize transition matrix.
Definition: tmat.c:134
void tmat_report(tmat_t *t)
Report the detail of the transition matrix structure.
Definition: tmat.c:262
void tmat_free(tmat_t *t)
RAH, add code to remove memory allocated by tmat_init.
Definition: tmat.c:275
void tmat_dump(tmat_t *tmat, FILE *fp)
Dumping the transition matrix for debugging.
Definition: tmat.c:72
