| The Apache Commons Math team is pleased to announce the commons-math3-3.5 release! |
| |
| The Apache Commons 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. |
| |
| Changes in this version include: |
| |
| New features: |
| o Added a way to build polyhedrons sets from a list of vertices and |
| facets specified using vertices indices. |
| o Simplified "FastMath#exp(double)" in order to avoid a potential |
| Java 1.5 JIT bug when calling with negative infinity as argument. Issue: MATH-1198. |
| o Added method "getQuadraticMean()" to "DescriptiveStatistics" |
| and "SummaryStatistics" which calculates the root mean square. Issue: MATH-1199. |
| |
| Fixed Bugs: |
| o Moved FastMathTestPerformance out of the main test tree, as is is |
| a benchmark rather than a test. Issue: MATH-1195. |
| o Fixed ignored method parameters in QRDecomposition protected methods. Issue: MATH-1191. |
| o Fixed wrong selection of line/polyhedron intersection point. Issue: MATH-1211. Thanks to Mike Zimmerman. |
| o Improved fix for corner cases in BSP-tree merging, when cut sub-hyperplanes vanish. Issue: MATH-1162. |
| o Fixed link to algorithm description in "PoissonDistribution#sample()". Issue: MATH-1209. Thanks to Jonathan Ogilvie. |
| o EmpiricalDistribution cumulativeProbability can return NaN when evaluated within a constant bin. Issue: MATH-1208. |
| o EmpiricalDistribution getKernel fails for buckets with only multiple instances of the same value. Issue: MATH-1203. |
| o "UnivariateSolverUtils#bracket(...)" sometimes failed to bracket |
| if a reached the lower bound. Issue: MATH-1204. |
| |
| Changes: |
| o Added Laguerre complex solve methods taking maxEval parameters. Issue: MATH-1213. |

| |
| Have fun! |
