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=0

Parameters

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 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.
