"isSparse()" method vs marker interfaces
----------------------------------------
Key: MATH-656
URL: https://issues.apache.org/jira/browse/MATH-656
Project: Commons Math
Issue Type: Improvement
Reporter: Gilles
Priority: Trivial
Fix For: 3.0
>From discussions on the "dev" ML, it seems that it would be advantageous to
>introduce a method "isSparse()" in "RealVector" and in "RealMatrix".
For "RealVector", it will make sense to use it to select between "iterator()"
and "sparseIterator()" in methods implemented in that class.
We could then remove the "SparseRealVector" and "SparseRealMatrix" interfaces.
