NAME
       mlib_VectorSumAbsDiff_U8_Sat, mlib_VectorSumAbsDiff_S8_Sat, mlib_VectorSumAbsDiff_S16_Sat, mlib_VectorSumAbsDiff_S32_Sat - sum of the abso-
       lute values of the differences of two vectors

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

       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 vector.

       y    Pointer to the first element of the second source vector.

       n    Number of elements in the vectors.

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