NAME
       mlib_SignalDTWVectorInit_F32 - initialization for vector data

SYNOPSIS
       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_SignalDTWVectorInit_F32(void *state,
	    const mlib_f32 **dref, mlib_s32 lref, mlib_s32 ndata,
	    mlib_s32 dtype, mlib_s32 delta, mlib_s32 local,
	    mlib_s32 slope);

DESCRIPTION
       The mlib_SignalDTWVectorInit_F32() 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).

       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.
