30 Each of these functions computes the Euclidean distances between two
31 vectors.
32
33
34 The following equation is used:
35
36 n-1
37 z[0] = { SUM (x[i] - y[i])**2 }**0.5
38 i=0

42 Each of the functions takes the following arguments:
43
44 z Pointer to the distance between the two vectors.
45
46
47 x Pointer to the first element of the first source vector.
48
49
50 y Pointer to the first element of the second source vector.
51
52
53 n Number of elements in the vectors.
54
55
57 Each of the functions returns MLIB_SUCCESS if successful. Otherwise it
58 returns MLIB_FAILURE.
