Inconsistent behaviour of constructors in ArrayRealVector class
---------------------------------------------------------------
Key: MATH-391
URL: https://issues.apache.org/jira/browse/MATH-391
Project: Commons Math
Issue Type: Bug
Affects Versions: 2.1
Reporter: Roman Werpachowski
ArrayRealVector(double[] d) allows to construct a zero-length vector, but
ArrayRealVector(double[] d, boolean copyArray) doesn't. Both should allow this
as zero-length vectors are mathematically well-defined objects and they are
useful boundary cases in many algorithms.
Zero-length vectors worked in version 2.0, they should be working in 2.1 as
well.
