Function Documentation

int32 tmat_chk_1skip (  tmat_t *  tmat  )

Checks that transition matrix arcs in the given object skip over at most 1 state. Returns: 0 if successful, -1 if check failed. Parameters: tmat  In: transition matrix

int32 tmat_chk_uppertri (  tmat_t *  tmat  )

Checks that no transition matrix in the given object contains backward arcs. Returns: 0 if successful, -1 if check failed. Parameters: tmat  In: transition matrix

void tmat_dump (  tmat_t *  tmat, FILE *  fp )

Dumping the transition matrix for debugging Parameters: tmat  In: transition matrix fp  In: file pointer

void tmat_free (  tmat_t *  t  )

RAH, add code to remove memory allocated by tmat_init Parameters: t  In: transition matrix

tmat_t* tmat_init (  const char *  tmatfile, float64  tpfloor, int32  breport, logmath_t *  logmath )

Initialize transition matrix Parameters: tmatfile  In: input file tpfloor  In: floor value for each non-zero transition probability breport  In: whether reporting the process of tmat_t

void tmat_report (  tmat_t *  t  )

Report the detail of the transition matrix structure. Parameters: t  In: transition matrix
