a |
|
octet |
b |
void |
octet (optional) |
Return value
[ Σ(ai*bi), Σ(ai-bi)^2, Σai^2, Σbi^2, Σai, Σbi, Σ(ai!=bi) ], or when bi===void, [ 0, Σai^2, Σai^2, 0, Σai, 0, Σ(ai!=0) ]
Description
Treats octets as vectors and computes sums
The dot product is r[0], the Euclidean distance is Math.sqrt(r[1]), and the cosine similarity is r[0]/(sqrt(r[2])*sqrt(r[3])).
