- Apache Commons Math 3.1.1 RELEASE NOTES
-
-The Commons Math team is pleased to announce the release of commons-math3-3.1.1
+The Commons Math team is pleased to announce the commons-math3-3.2 release!
The Math project is a library of lightweight, self-contained mathematics and statistics components addressing the most common practical problems not immediately available in the Java programming language or commons-lang.
-This is a point release: It fixes a bug that renders version 3.1 unusable
- in some situations (see details below).
-
Changes in this version include:
+New features:
+o Added Multivariate Normal Mixture Model Fitting by Expectation Maximization. Issue: MATH-817. Thanks to Jared Becksfort.
+o Added a way to trigger only increasing or decreasing events in ODE integration. Issue: MATH-811.
+o Added array-scaling methods to MathArrays. Issue: MATH-946. Thanks to Jared Becksfort.
+o Added the Lévy distribution. Issue: MATH-460. Thanks to Andrew Waterman.
+o Implementations for inverse error function and inverse complementary
+ error functions have been added. Issue: MATH-948.
+o Added utilities for prime numbers. Issue: MATH-845. Thanks to Sébastien Riou.
+o Check bounds in multi-start vector optimizers. Issue: MATH-914.
+o Added discrete distributions. Issue: MATH-941. Thanks to Piotr Wydrych.
+o Added Hermite interpolator for RealFieldElement instances.
+o Added RealFieldElement interface to represent anything that is
+ real number like, implemented by both Decimal64, Dfp and DerivativeStructure.
+o Added partial derivatives computation for 3D vectors and rotations.
+o Added accurate linear combination of DerivativeStructure instances,
+ avoiding cancellation.
+o Added conversion of gradients and Hessians from spherical to Cartesian
+ coordinates in 3D.
Fixed Bugs:
-o MATH-924: Added a (minimal) "DiagonalMatrix" implementation, such that the
- case of a large number of uncorrelated observations is handled
- efficiently.
-
-
-
-For complete information on Commons Math, including instructions on how to submit bug reports,
-patches, or suggestions for improvement, see the Apache Commons Math website:
+o Fixed inverse cumulative probability for uniform distribution. Issue: MATH-957. Thanks to Evan Ward.
+o "SpearmansCorrelation" now works correctly in case of a provided
+ "NaturalRanking" with a "NaNStrategy.REMOVED" strategy and the input
+ data contains NaN values. From version 4.0 onwards this strategy will
+ not be supported anymore. Issue: MATH-891.
+o Fixed Complex.reciprocal() for zero argument. Issue: MATH-934.
+o AbstractRealMatrix will now check for rectangular input arrays in
+ its copySubMatrix methods. Issue: MATH-862.
+o Increment iteration counter in optimization algorithms. Issue: MATH-949.
+o Fixed missing update in ODE event handlers, when a RESET_STATE is triggered. Issue: MATH-950.
+o Fixed infinite loop when NaN occurs in singular value decomposition. Issue: MATH-947.
+o Extended ranges for FastMath performance tests. Issue: MATH-580.
+o Finalized implementation of diagonal matrix. Issue: MATH-925.
+o Added rank revealing QR decomposition. Issue: MATH-630. Thanks to Christopher Nix.
+o ArrayFieldVector can now be constructed from any FieldVector. Issue: MATH-570. Thanks to Arne Plöse.
+o Improved checking of null vector elements. Issue: MATH-861. Thanks to Sébastien Brisard.
+o Fixed generation of long random numbers between two bounds. Issue: MATH-936.
+o Fixed creation of generic array. Issue: MATH-942. Thanks to Piotr Wydrych.
+o Fixed abstract test class naming that broke ant builds. Issue: MATH-940. Thanks to Piotr Wydrych.
+o Allow covariance to be computed for one-dimensional variables. Issue: MATH-939. Thanks to Piotr Wydrych.
+o Fixed accuracy of 3D Line.revert(). Issue: MATH-938.
+o Improved javadoc to explain how switching functions should
+ behave across events in ODE events detection. Issue: MATH-937.
+o Fixed DerivativeStructure.atan2 for special cases when both arguments are +/-0. Issue: MATH-935.
+o Improved class javadoc wrt convergence criteria and added
+ additional constructors to override the default epsilon and cut-off
+ values in class "SimplexSolver". Issue: MATH-930.
+o Fixed truncated value in "MultivariateNormalDistribution". Issue: MATH-929. Thanks to Piotr Wydrych.
+o Made "BitStreamGenerator" implement the "Serializable" interface. Issue: MATH-927. Thanks to Dennis Hendriks.
+
+Changes:
+o Replaced hard-coded numbers in "LevenbergMarquardtOptimizer". Issue: MATH-956.
+o Fixed loading of test file when path contains a space. Issue: MATH-955. Thanks to Evan Ward.
+o Improved speed of FastMath.abs methods for all signatures, by removing branching. Issue: MATH-954. Thanks to Charles Cooper.
+o Improved speed of several FastMath methods. Issue: MATH-953. Thanks to Charles Cooper.
+o Improved speed of FastMath copysign methods. Issue: MATH-951. Thanks to Charles Cooper.
+o Made EmpiricalDisribution smoothing kernel pluggable. Issue: MATH-671.
+o Allow direct use of SummaryStatistics in one-way ANOVA. Issue: MATH-877. Thanks to Peter Andrews.
+o Normal distribution now uses a direct implementation of the
+ inverse error function to compute inverse cumulative probability
+ instead of relying on a numerical solver. This is much faster,
+ more accurate and does not need convergence threshold.
+o Throw "MathUnsupportedOperationException" from optimizers that do
+ not support constraints (previous behaviour was to silently ignore
+ the "SimpleBounds" argument). Issue: MATH-933.
+o Greater efficiency in "UnitSphereRandomVectorGenerator". Issue: MATH-931. Thanks to Sean Owen.
