DESCRIPTION
Each of these functions computes the average of two vectors.
It uses the following equation:
z[i] = (x[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:
z Pointer to the first element of the destination vector.
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.
