Various distance methods in "Vector3D"
--------------------------------------
Key: MATH-263
URL: https://issues.apache.org/jira/browse/MATH-263
Project: Commons Math
Issue Type: New Feature
Reporter: Gilles
Priority: Minor
Hi.
As was discussed in the ML (cf. '[math] "equals" in "Vector3D"' thread), it
would be useful to add the various distance methods: L1 norm, L2 norm,
L-infinity norm.
One suggestion has been to use an enum:
enum Norm { L_0, L_1, L_2, L_infinity };
static double distance(Vector3D a, Vector3D b, Norm n) { ... }
Another, to define several methods:
a.distance1(b) { ... }
a.distance(b) { ... }
a.distanceInf(b) { ... }
At the cost of longer typing (but maybe there are other advantages) the above
could also be static.
Best,
Gilles
