double dotProduct(RealVector)
As first reported by Bill Barker, these tests fail with the current default implementation (in RealVector) as well as the sparse implementation (in OpenMapRealVector).

In org.apache.commons.math3.linear.RealVectorAbstractTest
- factored out unit tests of RealVector RealVector.set(double),
- created unit tests of double[] RealVector.toArray(),
- factored out unit tests of RealVector RealVector.unitVector(),
- factored out unit tests of void RealVector.unitize(),
- created unit tests of Iterator<RealVector.Entry> RealVector.iterator().
In org.apache.commons.math3.linear.ArrayRealVector, removed unnecessary overrides of unitVector() and unitize().
In org.apache.commons.math3.linear.RealVector
- unitVector() and unitize() now throw an ArithmeticException when the norm is 0 (as specified in the Javadoc),
- the returned iterator() returns NoSuchElementException as specified in the general contract of iterators.

This class implements the Hermite polynomial interpolation method, which
can match function derivatives in addition to function value at sampling
points. The implementation is done for vector-valued functions.

- modified OpenMapRealVector.ebeMultiply() and ebeDivide() to handle
special cases 0d * NaN, 0d * Infinity, 0d / 0d and 0d / NaN.
- added implementation of isNaN() and isInfinite() to
SparseRealVectorTest.SparseRealVectorTestImpl in order to allow for testing
of OpenMapRealVector.ebeMultiply() and ebeDivide() with mixed types.

Parameterized "CurveFitter" with the type of the fitting function. Updated subclasses
"PolynomialFitter", "HarmonicFitter", "GaussianFitter" accordingly.

- In RealVectorTest.TestVectorImpl, removed add(RealVector) and
subtract(RealVector), as they prevented testing of default implementations
(provided in the RealVector abstract class).
- In RealVectorAbstractTest, extracted unit tests for
+ RealVector.add(RealVector),
+ RealVector.subtract(RealVector),
+ RealVector.ebeMultiply(RealVector),
+ RealVector.ebeDivide(RealVector).
These tests fail with OpenMapRealVector. This is identified as a bug (see
MATH-803).

- testSubVectorInvalidIndex1(),
- testSubVectorInvalidIndex2(),
- testSubVectorInvalidIndex3(),
- testSubVectorInvalidIndex4()
from RealVectorAbstractTest.testDataInOut(). This test revealed that
positivity of the number of elements was not checked for in
RealVector.getSubVector(int, int).
This is corrected, and a NotPositiveException is now thrown (corresponding
error message has been added to LocalizedFormats).

RealVectorTest.testAddToEntryInvalidIndex2() revealed a bug in
ArrayRealVector.addToEntry(int, double) (method used to throw wrong type of
exception).

- defined class variables data1 and data2 for the creation of test vectors.
Attention has been paid to "special" values, which are interspersed with
"normal" values (see e.g. sparse vectors).
- created testGetDimension().
- created testGetEntry().

- some methods are not implemented by RealVector, so they should not be
tested: added @Ignore annotations in RealVectorTest.
- in RealVectorAbstractTest, extracted
+ testAppendVector()
+ testAppendScalar()
from testDataInOut().
