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.
o Added Laguerre complex solve methods taking maxEval parameters. Issue: MATH-1213.
Have fun!
