(ArmA3 1.22)Algorithm:
Vector1 = [x1,y1,z1]; Vector2 = [x2,y2,z2]; Result = ((x1 * x2) + (y1 * y2) + (z1 * z2))/((sqrt (x1 ^ 2 + y1 ^ 2 + z1 ^ 2))*(sqrt (x2 ^ 2 + y2 ^ 2 + z2 ^ 2)))Given two vectors of attributes, A and B, the cosine similarity, cos(θ), is represented using a dot product and magnitude. The resulting similarity values indicating intermediate similarity or dissimilarity between two vectors.
