Move regularize anywhere more appropriate #285
Description
The regularizeValues function is located in Interpolation.Approximation. While it is currently only used here, it is of bread interest to have this function available on a more global layer. It could be moved to the Seq/List/Array/Vector modules, or to its own source file in the Signal namespace.
Function
Zipping, sorting, aggregating at ties
let xData = [2;2;1;3]
let yData = [8;9;1;4]
regularizeValues xData yData Seq.mean
val it: seq<float * float> = seq [(1.0, 1.0); (2.0, 8.5); (3.0, 4.0)]

Agreed that
regularizeValueshas broad utility beyond interpolation. Here's a concrete migration path:Where it is now:
Interpolation.Approximation.regularizeValues(line ~2173 ofInterpolation.fs)Proposed move: Add the function to
FSharp.Stats.Array,Seq, andListmodules (or a shared helper module) with a more descriptive name — something likesortAndAggregateByKeyorgroupByKeyAndAggregate. The signature would generalise naturally:Backward compatibility: Keep
Interpolation.Approximation.regularizeValuesas a thin wrapper calling the new location, marked[<Obsolete>]if desired.Benefit beyond interpolation: The function is also useful for histogramming, signal resampling, and any workflow where duplicate keys need aggregating before downstream processing — so
Seq/Arrayfeels like the right home.Happy to implement this as a PR if maintainers agree on the target location and naming.
