It incorporates three bug fixes since version +3.6. The minimum version of the Java platform required to compile and use +Commons Math 3.6.1 is Java 5. -New features: -o Added a RotationConvention enumerate to allow specifying the semantics - or axis/angle for rotations. This enumerate has two values: - VECTOR_OPERATOR and FRAME_TRANSFORM. Issue: MATH-1302,MATH-1303. -o Added a field-based version of Ordinary Differential Equations framework. - This allows integrating ode that refer to RealField elements instead of - primitive double, hence opening the way to use DerivativeStructure to - compute partial differential without using variational equations, or to solve - ode with extended precision using Dfp. Issue: MATH-1288. -o Added a nth order Brent solver for general real fields, replacing the former - solver that was restricted to Dfp fields only. -o New "Range" inner class of "o.a.c.m.util.IntegerSequence". Issue: MATH-1286. -o "AggregateSummaryStatistics" can now aggregate any kind of - "StatisticalSummary".

Issue: MATH-1278. -o Added negative zero support in FastMath.pow. Issue: MATH-1273. Thanks to Qualtagh. -o Various SOFM visualizations (in package "o.a.c.m.ml.neuralnet.twod.util"): - Unified distance matrix, hit histogram, smoothed data histograms, - topographic error, quantization error. Issue: MATH-1270. -o New interfaces to be implemented by algorithms that visualizes properties - of a "NeuronSquareMesh2D" (package "o.a.c.m.ml.neuralnet.twod.util").

Issue: MATH-1265. -o "MapUtils" (package "o.a.c.m.ml.neuralnet"): Method to sort units according to distance - from a given vector. Issue: MATH-1264. -o Accessor (class "o.a.c.m.ml.neuralnet.twod.NeuronSquareMesh2D"). Issue: MATH-1263. -o New "IntegerSequence" class (in package "o.a.c.m.util") with "Incrementor" inner class. Issue: MATH-1259. -o "Neuron" class (package "o.a.c.m.ml.neuralnet"): added methods that can be used - to assess concurrency performance. Issue: MATH-1250. -o Method "cosAngle" in "o.a.c.m.util.MathArrays". Issue: MATH-1244. +Changes in this version include: Fixed Bugs: -o Improved performance and accuracy of 2-sample KolmogorovSmirnov tests. Issue: MATH-1310. -o Detect start failures with multi-step ODE integrators. Issue: MATH-1297. -o Fixed stability issues with Adams-Bashforth and Adams-Moulton ODE integrators. - The integrators did not estimate the local error properly and were sometimes - stuck attempting to reduce indefinitely the step size as they thought the - error was too high. Thanks to Julien Queyrel. -o Increased default value for number of allowed evaluations in - "o.a.c.m.optim.univariate.BracketFinder". Issue: MATH-1295. Thanks to Luke Lindsay. -o Fixed potential race condition in PolynomialUtils#buildPolynomial in - case polynomials are generated from multiple threads. Furthermore, the - synchronization is now performed on the coefficient list instead of the class. Issue: MATH-1294. Thanks to Kamil Włodarczyk. -o Fixed FastMath.exp that potentially returned NaN for non-NaN argument. Issue: MATH-1269. -o Updated reference in ZipfDistribution's javadoc. Issue: MATH-1285. Thanks to Pim van der Hoorn. -o Fixed "Gamma#gamma(double)" for negative values smaller than -20. Issue: MATH-1283. Thanks to Jean Noel Delavalade. -o Fixed javadoc of methods {floorDiv,floorMod} in class "FastMath". Issue: MATH-1237. Thanks to Ken Williams. -o Check precondition (class "o.a.c.m.random.EmpiricalDistribution"). Issue: MATH-1279. -o Fixed incorrect Kendall's tau coefficient calculation due to internal integer overflow. Issue: MATH-1277. Thanks to Marc Rosen. -o Fixed split/side inconsistencies in BSP trees. Issue: MATH-1266. -o Avoid overflow in "Fraction" (multiplication or division by an int). Issue: MATH-1261. Thanks to Osamu Ikeuchi. -o Added check for equal array lengths to distance measure functions. Issue: MATH-1258.

Issue: MATH-1255. -o ResizableDoubleArray constructor does not work with double array of size 1. Issue: MATH-1252. Thanks to John Bay. -o Fixed initial value of "number of calls" counter in class "KohonenUpdateAction" - (package "o.a.c.m.ml.neuralnet.sofm"). Issue: MATH-1251. -o Removed unnecessary allocations in "BigFraction" (package "o.a.c.m.fraction"). Issue: MATH-1248. Thanks to Chris Popp. -o Fixed error in computing discrete distribution of D statistics for small-sample - 2-sample Kolmogorov-Smirnov tests. Error was causing incorrect p-values returned - by exactP and monteCarloP methods (used by default for small, mid-size samples). Issue: MATH-1245. -o "KolmogorovSmirnovTest#ksSum(...)" returned wrong result in case the provided - t-parameters was zero. This affected the calculation of "approximateP(...)" for - identical samples. Issue: MATH-1240. -o Improved performance to calculate the two-sample Kolmogorov-Smirnov test - via monte carlo simulation ("KolmogorovSmirnovTets#monteCarloP(...)"). Issue: MATH-1242. Thanks to Otmar Ertl. -o A "StackOverflowException" was thrown when passing Double.NaN or infinity - to "Gamma#digamma(double)" or "Gamma#trigamma(double)".

Changes: -o Modified 2-sample KolmogorovSmirnovTest to handle ties in sample data. By default, - ties are broken by adding random jitter to input data. Also added bootstrap method - analogous to ks.boot in R Matching package. Issue: MATH-1246. -o Added bootstrap method to KolmogorovSmirnov test. Issue: MATH-1246. -o Added constructors taking sample data as arguments to enumerated real and integer distributions. Issue: MATH-1287. -o Improved performance of sampling and inverse cumulative probability calculation - for geometric distributions.
