| Oct 10, 2014 at 10:52 | comment | added | Ymareth | FYI - The actual use case concerns lists of times (represented by "HH:MM:SS.sss" strings, Mathematica's TimeObjects being woefully slow as yet) where I'm looking for nearly simultaneous events. I convert these to Reals using {3600, 60, 1}.ToExpression[StringSplit[#, ":"]]&. This is a lot faster than using DateDifference. | |

| Oct 9, 2014 at 18:37 | comment | added | Junho Lee | @Mr.Wizard Just I tried with simple code.:) | |
| Oct 9, 2014 at 18:36 | comment | added | Junho Lee | @Mr.Wizard You right. It is just show that my code is not much slow. | |
| Oct 9, 2014 at 18:29 | comment | added | Mr.Wizard | Nice idea, but I think that the integer lists were only an example in which case this enumeration will not be robust. Even for integers the operation will slow as n grows. Consider e.g. {a, b} = List @@ RandomInteger[1*^7, {2, 1000}]; and then distanceInt[a, b, 2500] | |
