This formula is used by a former coworker of mine to perform cluster analysis:
He has no idea why it functions. Its purpose is to determine the separation between a few points. I only get one result when I run the equation without the. I get another when I run it with it.
Normal distance formula: A2 + B2 = C2. I'm assuming this applies to several points in a row. Is this essentially performing each point in each row?
