DESCRIPTION
Each of these functions performs an in-place averaging of
two vectors. It uses the following equation: xz[i] = (xz[i] + y[i] + 1) / 2SunOS 5.11 Last change: 23 May 2007 1
mediaLib Library Functions mlib_VectorAve_U8(3MLIB)
where i = 0, 1, ..., (n - 1) for real data; i = 0, 1, ...,
(2*n - 1) for complex data.
PARAMETERS
Each of the functions takes the following arguments: xz Pointer to the first element of the first source and destination vector.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.
