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 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.
