mediaLib Library Functions    mlib_VectorSumAbsDiff_U8_Sat(3MLIB)



NAME
     mlib_VectorSumAbsDiff_U8_Sat,  mlib_VectorSumAbsDiff_S8_Sat,
     mlib_VectorSumAbsDiff_S16_Sat, mlib_VectorSumAbsDiff_S32_Sat
     - sum of the absolute values of the differences of two  vec-
     tors

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

     mlib_status mlib_VectorSumAbsDiff_U8_Sat(mlib_d64 *z,
          const mlib_u8 *x, const mlib_u8 *y, mlib_s32 n);


     mlib_status mlib_VectorSumAbsDiff_S8_Sat(mlib_d64 *z,
          const mlib_s8 *x, const mlib_s8 *y, mlib_s32 n);


     mlib_status mlib_VectorSumAbsDiff_S16_Sat(mlib_d64 *z,
          const mlib_s16 *x, const mlib_s16 *y, mlib_s32 n);


     mlib_status mlib_VectorSumAbsDiff_S32_Sat(mlib_d64 *z,
          const mlib_s32 *x, const mlib_s32 *y, mlib_s32 n);


DESCRIPTION
     Each of these functions computes the  sum  of  the  absolute
     values of the differences of two vectors.


     The following equation is used:

              n-1
       z[0] = SUM |x[i] - y[i]|
              i=0


PARAMETERS
     Each of the functions takes the following arguments:

     z    Pointer to the sum of the absolute differences  between
          two vectors.


     x    Pointer to the first element of the first  source  vec-
          tor.


     y    Pointer to the first element of the second source  vec-
          tor.

     n    Number of elements in the vectors.


RETURN VALUES
     Each of the functions returns  MLIB_SUCCESS  if  successful.
     Otherwise it returns MLIB_FAILURE.
