mediaLib Library Functions    mlib_SignalDTWVectorInit_F32(3MLIB)



NAME
     mlib_SignalDTWVectorInit_F32  -  initialization  for  vector
     data

SYNOPSIS
     cc [ flag... ] file... -lmlib [ library... ]
     #include 

     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  alloca-
     tion  and  global initialization. Per DTW function call ini-
     tialization 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.
