+
+Users of version 2.1 are encouraged to upgrade to 2.2, as this release
includes some important bug fixes.
+
+See the detailed list of changes below for full description of all bug fixes
and enhancements.
+
+This release contains some minor compatibility breaks with version 2.1 in some
internal classes but none
+ of them are in the public API:
+ the MessagesResources_fr class has been removed (replaced by a properties
file);
+ the arguments of the EventState.reinitializeBegin method have changed;
+ some private fields in AbstractStepInterpolator have been replaced.
+
+The major new features are:
+ a new FastMath class, both faster, more accurate and with a few additional
functions than StrictMath and Math;
+ a new package for floating point arbitrary precision computing, including
high level functions like exponential, sine, square root ...;
+ new linear and tricubic interpolators;
+ a new Gaussian curve fitter;
+ a new erfc function;
+ characteristic support for distributions;
+ a set of new Well Equidistributed Long-period Linear (WELL) random generators.
Changes in this version include:
New features:
-o MATH-357: Implementation of bicubic interpolation.
-o Added a way to compute both the final state in an Initial Value Problem (IVP)
- for Ordinary Differential Equations (ODE) and its derivatives with
respect to
- initial state and with respect to some problem parameters. This allows
wrapping
- ODE solvers into optimization or root finding algorithms, which in
turn can be
- used to solve Boundary Value Problems (BVP). There are no
implementations (yet)
- of BVP solvers in the library.
-o MATH-323: Added SemiVariance statistic. Thanks to Larry Diamond.
-o MATH-341: Added a warning in the getCoefficients method documentation for
- PolynomialFunctionLagrangeForm. Computation may be ill-conditioned
- so this method should be used with care.
-o MATH-340: Fixed an error in BigFraction multiplication for large numerators
that don't
- fit in a primitive int.
-o MATH-334: Added min/max getters for real vectors (not yet in the RealVector
interface for
- compatibility purposes, but in the AbstractRealVector abstract class).
-o MATH-321: Singular Value Decomposition now computes either the compact SVD
(using only
- positive singular values) or truncated SVD (using a user-specified
maximal
- number of singular values).
-o MATH-300: Added support for multidimensional interpolation using the robust
microsphere algorithm. Thanks to Gilles Sadowski.
-o MATH-287: Added support for weighted descriptive statistics. Thanks to
Matthew Rowles.
-o Added normalizeArray method to MathUtils.
+o MATH-364: Added complementary error function, erfc. Thanks to Christian
Winter.
+o MATH-385: Added characteristic support to distributions, including methods
to return numerical
+ estimates of the mean and variance and upper and lower bounds of
support. In version 2.2,
+ methods returning distribution characteristics have been added only to
the implementation
+ classes. In version 3, supporting methods have been added to the
abstract base classes
+ and distribution interfaces.
+o MATH-440: Created "MathUserException" class to convey cause of failure
between
+ layers of user code separated by a layer of Commons-Math code.
+o MATH-419: Added new random number generators from the Well Equidistributed
Long-period Linear (WELL).
+o MATH-412: Added the dfp library providing arbitrary precision floating
point computation in the spirit of
+ IEEE 854-1987 (not exactly as it uses base 1000 instead of base 10).
In addition to finite numbers,
+ infinities and NaNs are available (but there are no subnormals). All
IEEE 854-1987 rounding modes and
+ signaling flags are supported. The available operations are +, -, *, /
and the available functions
+ are sqrt, sin, cos, tan, asin, acos, atan, exp, log. Thanks to Bill
Rossi.
+o MATH-375: Added faster and more accurate version of traditional
mathematical functions in a FastMath
+ class intended to be a drop-in replacement for java.util.Math at
source-level. Some functions
+ still directly delegates to Math but this will improve with time. Some
functions like exp
+ may be twice as fast (even 3 times faster on some processors). Sine,
cosine or power functions
+ show typical speedups of 1.5 times faster or more. Thanks to Bill
Rossi.
+o MATH-400: Added support for Gaussian curve fitting. Thanks to J. Lewis
Muir.
+o MATH-388: Added a feature allowing error estimation to be computed only on
a subset of
+ Ordinary Differential Equations, considered as the main set, the
remaining equations
+ being considered only as an extension set that should not influence
the ODE integration
+ algorithm
+o MATH-379: Created "MultidimensionalCounter" class.
+o MATH-378: Implementation of linear interpolation. Thanks to Matthew Rowles.
+o MATH-370: Added new "equalsIncludingNaN" methods that have the same
semantics as the old "equals" methods.
+ The semantics of the old methods will be modified (in the next major
release) such that
+ NaNs are not considered equal (to be more compliant with IEEE754).
+o MATH-366: Implementation of tricubic interpolation.
Fixed Bugs:
-o MATH-360: Fix use of wrong variable in
SmoothingBicubicSplineInterpolatorTest.testPreconditions()
-o MATH-335: Fraction.hashCode() implementation was not fully consistent with
Fraction.equals().
- Changed hashCode() to use fields directly to agree with equals().
-o MATH-282: Resolved multiple problems leading to inaccuracy and/or failure
to compute Normal,
- ChiSquare and Poisson probabilities, Erf and Gamma functions. Made
Brent solver
- absolute accuracy configurable for all continuous distributions.
-o MATH-347: Fixed too stringent interval check in Brent solver: initial guess
is now
- allowed to be at either interval end
-o MATH-358: Fixed an error in events handling in ODE solvers. In some rare
cases, events
- occurring close to a step start were handled without truncating the
step, making
- them appear as is they occurred close to the step end
-o Fixed a problem with getInterpolatedDerivatives returning zero derivatives
when
- an ODE step handler is configured to not use interpolation. It now
returns a
- constant but non-zero value consistent with at least one point inside
the step
-o MATH-344: Fixed wrong return values when enpoints are roots in Brent solver
with
- a user provided initial guess
-o MATH-343: Fixed a missing bracketing check of initial interval in Brent
solver.
-o MATH-342: In SVD, the matrices passed to EigenDecomposition are now
symmetric
- by construction (rather than simply by definition). In
EigenDecomposition,
- once the tridiagonal form is obtained, the non-significant elements are
- set to 0.
-o MATH-333: A EigenDecompositionImpl simplified makes it possible to compute
- the SVD of a singular matrix (with the right number of elements in
- the diagonal matrix) or a matrix with singular value(s) of multiplicity
- greater than 1.
-o Fixed a spurious exception in EigenDecompositionImpl when a 3x3 block
- had two identical eigenvalues.
-o MATH-338: Fixed automatic step initialization in embedded Runge-Kutta
integrators.
- The relative tolerance setting was never used, only the absolute
tolerance
- was used. Thanks to Vincent Morand.
-o MATH-329: Fixed regression in Frequency.getPct(Object) introduced in 2.0.
Cumulative
- percent was being returned for Object arguments in place of percent.
-o MATH-320: Fixed Singular Value Decomposition solving of singular systems.
-o MATH-326: Fixed a wrong implementation of the Linf norm in vectors. Thanks
to Jake Mannix.
-o MATH-324: Fixed a convergence discrepancy with respect to theory in
Gragg-Bulirsch-Stoer
- integrator. Thanks to Vincent Morand.
-o Fixed a wrong dimension check in SVD solver. Thanks to Dimitri Pourbaix.
-o MATH-313: Added composition features for real functions. Thanks to Jake
Mannix.
-o MATH-312: Added mapping and iteration methods to vectors. Provided a
default implementation
- for the numerous simple methods in the RealVectorInterface. Thanks to
Jake Mannix.
-o MATH-322: Fixed an error in handling very close events in ODE integration.
-o MATH-305: Fixed an overflow error in MathUtils.distance that was causing
KMeansPlusPlusClusterer
- to fail with a NullPointerException when component distances between
points
- exceeded Integer.MAXVALUE. Thanks to Erik van Ingen.
-o MATH-318: Fixed an index computation error in eigen decomposition. Once
again, kudos to Dimitri
- for debugging this. Thanks to Dimitri Pourbaix.
-o MATH-308: Fixed an ArrayIndexOutOfBoundsException in eigen decomposition.
Kudos to Dimitri
- for debugging this, it was really difficult. Thanks to Dimitri
Pourbaix.
-o MATH-309: Fixed parameter test in RandomDataImpl#nextExponential. The
method now throws
- IllegalArgumentException for mean = 0. Thanks to Mikkel Meyer
Andersen.
-o MATH-306: Removed dead code from Complex#divide. Thanks to Joerg Huber.
-o MATH-294: Fixed implementation of RandomDataImpl#nextPoisson by
implementing an alternative
- algorithm for large means.
-o MATH-298: Fixed implementation of EmpiricalDistributionImpl#getUpperBounds
to match
- interface contract. Added getGeneratorUpperBounds method to
- EmpiricalDistributionImpl providing previous behavior.
-o MATH-296: Fixed wrong results on Loess interpolation, also added a way to
set weights
- for smoothing and to ignore zero weights for coefficients computation
Thanks to Eugene Kirpichov.
-o MATH-293: Fixed a OutOfBoundException in simplex solver when some
constraints are tight. Thanks to Benjamin McCann.
-o MATH-291: Fixed misleading number formats in error messages for adaptive
- stepsize integrators. Thanks to Sebb.
-o MATH-290: Fixed a NullPointerException in simplex solver when no solution
is possible
- and some constraints are negative. Thanks to Benjamin McCann.
-o MATH-289: Removed an unused argument in a private method in simplex solver.
-o MATH-288: Fixed an error induced by entries set to 0 in simplex solver.
Thanks to Benjamin McCann.
-o MATH-286: Fixed an error leading the simplex solver to compute the right
solution
- but return another one. Thanks to Benjamin McCann.
-o MATH-283: Prevent infinite loops in multi-directional direct optimization
method when
- the start point is exactly at the optimal point. Thanks to Michael
Nischt.
-o MATH-297: Prevent possible zero divides on eigenvectors of indefinite
matrices Thanks to Axel Kramer.
+o MATH-505: TestUtils is thread-hostile. Deprecate the getters and setters.
+o MATH-471: MathUtils.equals(double, double) does not work properly for floats
+ - add equivalent (float, float) methods and basic tests
+o MATH-467: Fixed an awkward statement that triggered a false positive
warning.
+o MATH-456: Modified erf (and erfc) to return extreme values for x with
abs(x) > 40.
+ For these arguments, the true value is indistinguishable from an
extrema as a double.
+o MATH-414: Modified NormalDistributionImpl.cumulativeProbability to return 0
or 1,
+ respectively for values more than 40 standard deviations from the mean.
+ For these values, the actual probability is indistinguishable from 0
or 1
+ as a double. Top coding improves performance for extreme values and
prevents
+ convergence exceptions.
+o MATH-380: Deprecated the whole ode.jacobians package. It is clumsy and
difficult to use. It will
+ be replaced by a completely rewritten implementation in 3.0, which
will be more tightly
+ bound to the top level ode package
+o MATH-426: Added a normalization feature to transform samples so they have
zero mean and unit standard deviation Thanks to Erik van Ingen.
+o MATH-429: Fixed k-means++ to add several strategies to deal with empty
clusters that may appear
+ during iterations
+o MATH-391: Fixed an error preventing zero length vectors to be built by some
constructors
+o MATH-421: Fixed an error preventing ODE solvers to be restarted after they
have been stopped by a discrete event
+o MATH-415: Fixed lost cause in MathRuntimeException.createInternalError.
Note that the message is still the default
+ message for internal errors asking to report a bug to commons-math
JIRA tracker. In order to retrieve
+ the message from the root cause, one has to get the cause itself by
getCause().
+o MATH-411: Modified multiple regression newSample methods to ensure that by
default in all cases,
+ regression models are estimated with intercept terms. Prior to the
fix for this issue,
+ newXSampleData(double[][]), newSampleData(double[], double[][]) and
+ newSampleData(double[], double[][], double[][]) all required columns
of "1's" to be inserted
+ into the x[][] arrays to create a model with an intercept term; while
newSampleData(double[], int, int)
+ created a model including an intercept term without requiring the
unitary column. All methods have
+ been changed to eliminate the need for users to add unitary columns to
specify regression models.
+ Users of OLSMultipleLinearRegression or GLSMultipleLinearRegression
versions 2.0 or 2.1 should either
+ verify that their code either does not use the first set of data
loading methods above or set the noIntercept
+ property to true on estimated models to get the previous behavior.
+o MATH-386: Added R-squared and adjusted R-squared statistics to
OLSMultipleLinearRegression.
+o MATH-392: Corrected the formula used for Y variance returned by
calculateYVariance and associated
+ methods in multiple regression classes
(AbstractMultipleLinearRegression,
+ OLSMultipleLinearRegression, GLSMultipleLinearRegression). These
methods previously returned
+ estimates of the variance in the model error term. New
"calulateErrorVariance" methods have
+ been added to compute what was previously returned by
calculateYVariance. Thanks to Mark Devaney.
+o MATH-406: Bug fixed in Levenberg-Marquardt (handling of weights).
+o MATH-405: Bug fixed in Levenberg-Marquardt (consistency of current).
+o MATH-377: Bug fixed in chi-square computation in
AbstractLeastSquaresOptimizer.
+o MATH-395: Fixed several bugs in "BrentOptimizer".
+o MATH-393: Fixed inconsistency in return values in
"MultiStartUnivariateRealOptimizer".
+o MATH-382: Fixed bug in precondition check (method
"setMicrosphereElements").
+o MATH-361: Improved localization of error messages.
+o MATH-376: Allow multiple optimizations with a default simplex.
+o MATH-352: Added a setQRRankingThreshold method to Levenberg-Marquardt
optimizer to improve robustness
+ of rank determination.
+o MATH-362: Fixed Levenberg-Marquardt optimizer that did not use the
vectorial convergence checker.
+ Now this optimizer can use either the general vectorial convergence
checker or its own
+ specialized convergence settings.
+o MATH-371: Fixed loss of significance error in PersonsCorrelation p-value
computation causing p-values
+ smaller than the machine epsilon (~1E-16) to be reported as 0. Thanks
to Kevin Childs.
+o MATH-369: Fix NullPointerException in BisectionSolver.solve(f, min, max,
initial) Thanks to Sasun Pundev.
+o MATH-368: Fix spelling of getSparcity [sic] method of OpenMapRealVector
+o MATH-367: Fix problem with the default sparseIterator when a RealVector has
exactly one non-zero entry Thanks to Albert Huang.
Changes:
-o MATH-356: Added method to clear the list of observations in CurveFitter.
-o MATH-332: Added density functions to remaining continuous distributions (F,
T, Weibull, Cauchy).
- As of Math 2.1, all continuous distributions implement density
functions. The HasDensity
- interface has been deprecated and in version 3.0, density(double) will
be added to the
- ContinuousDistribution interface. Thanks to Mikkel Meyer Andersen.
-o MATH-337: Changed equals() methods to use instanceof check rather than
catching ClassCastException;
- this also allows some null checks to be omitted.
-o MATH-336: Removed unnecessary null checks in equals methods.
-o MATH-239: Added MathUtils methods to compute gcd and lcm for long
arguments. Thanks to Christian Semrau.
-o MATH-287: Added support for weighted univariate statistics. Thanks to
Matthew Rowles.
-o MATH-315: Added generationsEvolved property to GeneticAlgorithm to track
the number of generations
- evolved by the evolve() method before reaching the StoppingCondition.
Thanks to Mikkel Meyer Andersen.
-o MATH-311: Changed probability calculations for Binomial, Poisson, and
Hypergeometric
- distributions to use Catherine Loader's saddle point approximations.
Thanks to Nipun Jawalkar.
+o MATH-384: Added a constructor and addValues(double[]) methods allowing
DescriptiveStatistics to
+ be initialized with values from a double[] array. Similarly enhanced
+ ResizeableDoubleArray.
+o MATH-448: Added a getUniqueCount() method to Frequency to return the number
of unique
+ values included in the frequency table. Thanks to Patrick Meyer.
+o MATH-420: Added toString() override to StatisticalSummaryValues.
+o MATH-417: Improved Percentile performance by using a selection algorithm
instead of a
+ complete sort, and by allowing caching data array and pivots when
several
+ different percentiles are desired
+o MATH-409: Made intercept / no intercept configurable in multiple regression
classes. By default, regression
+ models are estimated with an intercept term. When the "noIntercept"
property is set to
+ true, regression models are estimated without intercepts.
+o MATH-361: Created package "exception" to contain the new exceptions
hierarchy.
+ Created package "exception.util": utilities for the exception classes
+ (e.g. managing the localization of error messages).
+ Default policy for dealing with invalid null references: raise a
+ "NullArgumentException" (subclass of "IllegalArgumentException").
+o MATH-310: Added random data generation methods to RandomDataImpl for the
remaining distributions in the
+ distributions package. Added a generic nextInversionDeviate method
that takes a discrete
+ or continuous distribution as argument and generates a random deviate
from the distribution.
+ Also added sampling methods based on the implementations in
RandomDataImpl to distributions.
+o MATH-365: Deprecated SmoothingBicubicSplineInterpolator and
SmoothingBicubicSplineInterpolatorTest.
+ Added BicubicSplineInterpolator and BicubicSplineInterpolatorTest.
+ Added SmoothingPolynomialBicubicSplineInterpolator and
SmoothingPolynomialBicubicSplineInterpolatorTest.
+ Added method to clear the list of observations in PolynomialFitter.
