Allocation of HMM structures.
Routines for allocation and initialisation of HMM structures. The name of the routines consists of three parts. The first part is alloc_ or init_. alloc_ routines first allocate, then initialise. init_ routines only fill in default values, allocation of memory should have been done. Return value for alloc_ routines is the structure or 0 on success, and NULL or -1 on allocation failure (already allocated memory then is freed). The second part of the name gives the structure it will work on (see hmmdef.c). Routines exist for the structure Mvg (mvg), Mvgs (mvgs), State (state), States (states) and Hmm (hmm). The third part of the name indicates the part of the structure that will be allocated or initialised. _struct routines only allocate the structure, not the substructures (Mvg for Mvgs, State for States, States and Mvgs for Hmm), nor the structures allocated by _aid routines. _val routines allocate or initialise HMM values as found in HMM files (mu, sigma, logsigprod, glob_ct for Mvg; weight, state2mvg, trans, bias, sum_ct, mixdim for State). For allocation of a _val routine a totally new structure (of which the size and/or description must be specified) is made. _aid routines allocate and initialise some vectors used in training and recognition (probability and selected arrays). _cts routines allocate or initialise the counts used in reestimation (training, _ct arrays). For both _aid and _cts routines, the allocation for the HMM values (_val routine) should have been done.
