DESCRIPTION
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=0PARAMETERS
Each of the functions takes the following arguments: z Pointer to the distance between the two vectors.x Pointer to the first element of the first source vec-
tor.y Pointer to the first element of the second source vec-
