*No.* In the context of (plain) {_}geometry{_}, please.
No application in the domains which you listed would add a dependency on
"Commons Geometry" for the sake of not implementing a method like
{{getIndicesOfOccurenceOfElement}} (that is trivial compared to functionality
needed to create such an application).
bq. no, I wouldn't create
getIndicesOfOccurenceOfElementSmallerThanOrEqualToThreeTimesTheLastElement(List<Double>
list).
That was the one _rhetorical_ question. There were real questions, such as how
one can determine what belongs in the API within a given scope, and the best
(most concise) way to provide some utility.
> Implement getIndicesOfOccurenceOfElement(Vector x, double element)
