EigenRand Versions Save

• Improved the performance of MultinomialGen.
• Implemented vectorization over parameters to some distributions (#46).
• Optimized the performance of double-type generators on NEON architecture.

Bug Fixes

• Fixed a bug where double-type generation with std::mt19937 fails compilation.
• Fixed a bug where UniformIntGen in scalar mode generates numbers in the wrong range.

• Now EigenRand supports ARM & ARM64 NEON architecture experimentally. Please report issues about ARM & ARM64 NEON.
• Now EigenRand has compatibility to Eigen 3.4.0.

• Now UniformRealGen generates accurate double values.
• Fixed a bug where non-vectorized double-type NormalGen would get stuck in an infinite loop.
• New overloading functions balanced and balancedLike which generate values over [a, b] were added.

• Now Eigen 3.3.4 - 3.3.6 versions are additionally supported.

• A compilation failure with some RNGs in double type was fixed.
• An internal function name plgamma conflict with one of SpecialFunctionsPacketMath.h was fixed.

• A default constructor for DiscreteGen was added.
• A problem with pcmplt in AVX was fixed.

• Compiling errors in the environment EIGEN_COMP_MINGW && __GXX_ABI_VERSION < 1004 was fixed.

• Potential cache conflict in generator was solved.
• Generator classes were added for efficient reusability.
• Multivariate distributions including Multinomial, Dirichlet, MvNormal, Wishart, InvWishart were added.
