NAME
mlib_SignalDTWVectorInit_S16 - initialization for vector data SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_SignalDTWVectorInit_S16(void *state, const mlib_s16 **dref, mlib_s32 lref, mlib_s32 ndata, mlib_s32 dtype, mlib_s32 sref, mlib_s32 delta, mlib_s32 local, mlib_s32 slope); DESCRIPTION
The mlib_SignalDTWVectorInit_S16() function initializes the internal state structure for dynamic time warping (DTW) of vector data. The init function performs internal state structure allocation and global initialization. Per DTW function call initialization is done in DTW function, so the same internal state structure can be reused for multiple DTW function calls. PARAMETERS
The function takes the following arguments: dref The reference data array. lref The length of the reference data array. ndata The length of each data vector. dtype The type of distance metric between data vectors. MLIB_DTW_L1NORM for L1 norm of difference (sum of absolute difference). MLIB_DTW_L2NORM for L2 norm of difference (Euclidean distance). sref The scaling factor of the reference data array, where actual_data = input_data * 2**(-scaling_factor). delta The delta in the endpoint constraints. local The type of the local continuity constraints. MLIB_DTW_ITAKURA for Itakura type constraints. slope The type of the slope weighting. MLIB_DTW_NONE for no slope weighting. state Pointer to the internal state structure. RETURN VALUES
The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
