Arne Plöse commented on MATH-643:
---------------------------------
@perl
http://perldoc.perl.org/functions/map.html
says that map evaluates a BLOCK or EXPR given to map. This is what
RealVector.map(...) does - nothing wrong with this.
But mapAdd(double d) is a simple addition of d to each element of the vector -
I would say name this mapping is wrong in this case.
{code}AbstractRealvector.mappAddToSelf(double d){code} uses internally mapping
so this may be OK - but I cant see any benefit from this.
I think the reason for ebe and map is only dotProduct|outherProduct|ebeMultiply
to make clear what the methods are doing.
By the way add(double[] v] should be renamend to ebeAdd(double[] v) to be
consistent with the naming scheme.
> Rename RealVector.map* to RealVector.ebe* (mapAdd(...) to ebeAdd(...) and
> mapAddToSelf(...) to ebeAddToSelf(...) for instance

> Key: MATH-643
> URL: https://issues.apache.org/jira/browse/MATH-643
> Project: Commons Math
> Issue Type: Improvement
> Affects Versions: 3.0
> Reporter: Arne Plöse
> Priority: Minor
>
> I think the map* methods have historical names. Today I would prefer ebe as
> prefix like ebeMultiply(...).
> This would describe the methods better from a users view.
> If this is a valid issue, I could provide a patch.
