Let we have a series of points (Xi,Yi) and want
to calculate the distance (metric) between points and object.
Distances
- Distances between each point (Xi,Yi) and fixed Point (X,Y).
- Distances between each point (Xi,Yi) and straight line (Y = a + b*X).
- Distances between each point (Xi,Yi) and next series of points (Xni,Yni).
- Distances between each point (Xi,Yi) and any function (defined by formula) f(Xi).
Distance is calculated as minimum distance between point (Xi,Yi) and function f(Xi)
using normal (Perpendicular from a point on a curve).
- Distances between each point (Xi,Yi) and any function (defined by formula) f(Xi).
Distance is calculated as projection value
abs(Yi -f(Xi).
The button <Copy> lets you put on the Clipboard:
- X,Y - point (Xi,Yi)
- L - distance between point (Xi,Yi) and function (curve)
- Xn,Yn - normal (or projection) on function.
