Euclidean distance = √ Σ(A i-B i) 2. The distance between the two hyperplanes is also the distance between the two points x1 and x2 where the hyperplane intersects the line through the origin and parallel to the normal vector a. 2.5.1 Write the vector, parametric, and symmetric equations of a line through a given point in a given direction, and a line through two given points. The distance function, known as a metric, must satisfy a collection of axioms. The metric should ideally be $0$ if there is an exact one-to-one correspondence between the points in the two sets, and increase monotonically as the difference (in some sense) between the two sets of points increases. To learn more, see our tips on writing great answers. Consider two sets of $N$ $n$-dimensiononal points each: $$\mathcal{X}= \lbrace \mathbf{x}_1,\mathbf{x}_2,\dots,\mathbf{x}_N \rbrace,$$, $$\mathcal{Y}= \lbrace \mathbf{y}_1,\mathbf{y}_2,\dots,\mathbf{y}_N \rbrace,$$.

Asking for help, clarification, or responding to other answers. If I understand correctly, you're asking people to judge the similarity of these patterns and the values of the coordinates don't have any meaning up to at least translations, possibly also rotations -- your measure should reflect this; otherwise you'd be introducing artificial dissimilarity that doesn't correspond to any dissimiliarity a person would perceive. Euclidean distance can be extended to an n-dimensional space in which each of the n dimensions is a variable used to compute the distance … That seems to do the job.
