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 vec‐
tors.
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.
