Example 1

Suppose we have collected 5 data points with 3 variables. The data matrix will look like: 
  X=[2,1,3,
    2,3,1,
    4,5,6,
    6,6,6
    7,5,3]
To calculate Euclidian distance between each pair of points, we use the following code: 
    PairWiseDistance(X,D,3); // 3 dimensions for 3 variables
Generated distance matrix has zero diagonal and is always symmetric.
