Each of these functions computes the Euclidean distances between two vectors.
The following equation is used:
n-1 z[0] = { SUM (x[i] - y[i])**2 }**0.5 i=0
Each of the functions takes the following arguments:
z
x
y
n
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
