Linear algebra

Major enhancements

  • Upgraded native libraries to Intel® OneAPI version 2023 Update 1.
  • Upgraded managed linear algebra library to LAPACK 3.9.1.
  • Support for indexing using range and index operators.

Other improvements

  • Improve performance for managed complex linear algebra.
  • Code quality and performance improvements in the machine translation of LAPACK.
  • Deconstruction of matrix decompositions into their component matrices.


General improvements

  • Complex number arithmetic is optimized to be on par with non-generic code.
  • Easier creation of complex numbers thanks to an implicit conversion from a 2-tuple to a complex number.
  • Deconstructors for complex and rational numbers.
  • New integration algorithm: double-exponential quadrature.
  • Automatic differentiation supports the new System.Math methods.

Equation solvers

  • New one-dimensional equation solver based on TOMS algorithm 487.
  • One-dimensional equation solvers can now restrict their search to a user-defined interval.
  • Improved robustness of one-dimensional equation solvers.

Special functions

  • New: Struve functions, which are the solutions of the inhomogeneous Bessel differential equations.
  • Improved accuracy and performance of various gamma-related functions.

Statistics and data analysis

Hypothesis tests

  • New: Fisher’s Exact Test for 2x2 and RxC contingency tables.
  • Breusch-Godfrey test for serial correlation in the residuals of a linear regression.

Probability distributions

  • New: DiscreteDistribution<T> that can sample from a finite set of arbitrary objects.
  • New continuous distributions: Johnson family of distributions, arcsine distribution, PERT distribution.
  • New properties of distributions: Entropy, Median, Mode, IsMultimodal, GetAllModes()
  • New LogProbability method for discrete distributions.
  • Gumbel (extreme value) distribution now allows modelling of the smallest or the largest extreme value.
  • New: Estimation of inverse Weibull and Gumbel distributions.
