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) / 2

       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 vector.

       n     Number of elements in the vectors.

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