• See also: Roadmap and Towards Math.NET Numerics Version 3.
• Major release with breaking changes
• All obsolete code has been removed
• Reworked redundancies, inconsistencies and unfortunate past design choices.
• Significant namespace simplifications (-30%).
• Linear Algebra:
  • Favor and optimize for generic types, e.g. Vector<double>.
  • Drop the .Generic in the namespaces and flattened solver namespaces.
  • F#: all functions in the modules now fully generic, including the matrix function.
  • F#: SkipZeros instead of the cryptic nz suffix for clarity.
  • Add missing scalar-matrix routines.
  • Optimized mixed dense-diagonal and diagonal-dense operations (500x faster on 250k set).
  • More reasonable choice of return structure on mixed operations (e.g. dense+diagonal).
  • Add point-wise infix operators .*, ./, .% where supported (F#)
  • Vectors explicitly provide proper L1, L2 and L-infinity norms.
  • All norms return the result as double (instead of the specific value type of the matrix/vector).
  • Matrix L-infinity norm now cache-optimized (8-10x faster).
  • Vectors have a ConjugateDotProduct in addition to DotProduct.
  • Matrix.ConjugateTransposeAndMultiply and variants.
  • Matrix Factorization types fully generic, easily accessed by new Matrix<T> member methods (replacing the extension methods). Discrete implementations no longer visible.
  • QR factorization is thin by default.
  • Matrix factorizations no longer clone their results at point of access.
  • Add direct factorization-based Solve methods to matrix type.
  • Massive iterative solver implementation/design simplification, now mostly generic and a bit more functional-style.
  • Renamed iterative solver stop criteria from 'criterium' to 'criterion'.
  • New MILU(0) iterative solver preconditioner that is much more efficient and fully leverages sparse data. ~Christian Woltering
  • Matrices/Vectors now have more consistent enumerators, with a variant that skips zeros (useful if sparse).
  • Matrix/Vector creation routines have been simplified and usually no longer require explicit dimensions. New variants to create diagonal matrices, or such where all fields have the same value. All functions that take a params array now have an overload accepting an enumerable (e.g. OfColumnVectors).
  • Generic Matrix/Vector creation using builders, e.g. Matrix<double>.Build.DenseOfEnumerable(...)
  • Create a matrix from a 2D-array of matrices (top-left aligned within the grid).
  • Create a matrix or vector with the same structural type as an example (.Build.SameAs(...))
  • Removed non-static Matrix/Vector.CreateMatrix/CreateVector routines (no longer needed)
  • Add Vector.OfArray (copying the array, consistent with Matrix.OfArray - you can still use the dense vector constructor if you want to use the array directly without copying).
  • More convenient and one more powerful overload of Matrix.SetSubMatrix.
  • Matrices/Vectors expose whether storage is dense with a new IsDense property.
  • Various minor performance work.
  • Matrix.ClearSubMatrix no longer throws on 0 or negative col/row count (nop)

  • Storage-aware non-inplace functional map on vectors and matrices
  • Pointwise power, exponential and natural logarithm for vectors and matrices.
  • Matrix positive-integer power
  • Matrix RemoveRow/RemoveColumn; more efficient InsertRow/InsertColumn
• Native Linear Algebra/Intel MKL:
  • Thin QR factorization uses MKL if enabled for all types (previously just double)
  • Sparse matrix CSR storage format now uses the much more common row pointer convention and is fully compatible with MKL (so there is nothing in the way to add native provider support).
  • Providers have been moved to a Providers namespace and are fully generic again.
  • Simpler provider usage: Control.UseNativeMKL(), Control.UseManaged().
  • MKL native provider now supports capability querying (so we can extend it much more reliably without breaking your code).
  • MKL native provider consistency, precision and accuracy now configurable (trade-off).
  • Native Provider development has been reintegrated into the main repository; we can now directly run all unit tests against local native provider builds. Covered by FAKE builds.

  • BUG: Fix hyper-geometric CDF semantics, clarify distribution parameters.
  • BUG: Fix Zipf CDF at x=1.

  • Thread-safe System.Random available again as SystemRandomSource.
  • Fast and simple to use static SystemRandomSource.Doubles routine with lower randomness guarantees.
  • Shared SystemRandomSource.Default and MersenneTwister.Default instances to skip expensive initialization.
  • Using thread-safe random source by default in distributions, Generate, linear algebra etc.

• Root Finding: Chebychev polynomial roots.
• Root Finding: Cubic polynomials roots. ~Candy Chiu
• Trig functions: common short names instead of very long names. Add sinc function.
• Excel functions: TDIST, TINV, BETADIST, BETAINV, GAMMADIST, GAMMAINV, NORMDIST, NORMINV, NORMSDIST, NORMSINV QUARTILE, PERCENTILE, PERCENTRANK.
• Special functions: BetaRegularized more robust for large arguments.
• Special functions: new GammaLowerRegularizedInv.
• New distance functions in Distance: euclidean, manhattan, chebychev distance of arrays or generic vectors. SAD, MAE, SSD, MSE metrics. Pearson's, Canberra and Minkowski distance. Hamming distance.

• BigInteger factorial
• Build:
  • FAKE-based build (in addition to existing Visual Studio solutions) to clean, build, test, document and package independently of the CI server.
  • Finally proper documentation using FSharp.Formatting with sources included in the repository so it is versioned and can be contributed to with pull requests.
  • NuGet packages now also include the PCL portable profile 47 (.NET 4.5, Silverlight 5, Windows 8) in addition to the normal .Net 4.0 build and PCL profile 136 (.Net 4.0, WindowsPhone 8, Silverlight 5, Windows 8) as before. Profile 47 uses System.Numerics for complex numbers, among others, which is not available in profile 136.
  • NuGet packages now also include a .NET 3.5 build of the core library.
  • IO libraries have been removed, replaced with new .Data packages (see list on top).
  • Alternative strong-named versions of more NuGet packages (mostly the F# extensions for now), with the .Signed suffix.
  • Reworked solution structure so it works in both Visual Studio 11 (2012) and 12 (2013).
  • We can now run the full unit test suite against the portable builds as well.

• F# BigRational Reciprocal, Power operator support (**), support for negative integer powers.
• F# functions now use the clearer Func suffix instead of just F if they return a function.
• Precision: reworked, now much more consistent. If you use AlmostEqual with numbers-between/ULP semantics, please do review your code to make sure you're still using the expected variant!. If you use the decimal-places semantics, you may need to decrement the digits argument to get the same behavior as before.
• Much less null checks, our code generally only throws ArgumentNullException if an unexpected null argument would not have caused an immediate NullReferenceException.
• Cases where ArgumentOutOfRangeExceptions where thrown with wrong arguments (i.e. no parameter name) now throw ArgumentException instead.

• BUG: fixing a bug in ArrayStatistics.Variance on arrays longer than 46341 entries.

2.6.0 - 2013-07-26

• See also: What's New in Math.NET Numerics 2.6
• Linear Curve Fitting: Linear least-squares fitting (regression) to lines, polynomials and linear combinations of arbitrary functions. Multi-dimensional fitting. Also works well in F# with the F# extensions.
• Root Finding:
  • Brent's method. ~Candy Chiu, Alexander Täschner
  • Bisection method. ~Scott Stephens, Alexander Täschner
  • Broyden's method, for multi-dimensional functions. ~Alexander Täschner
  • Newton-Raphson method.
  • Robust Newton-Raphson variant that tries to recover automatically in cases where it would fail or converge too slowly. This modification makes it more robust e.g. in the presence of singularities and less sensitive to the search range/interval.
  • All algorithms support a TryFind-pattern which returns success instead of throwing an exception.
  • Special case for quadratic functions, in the future to be extended e.g. to polynomials.
  • Basic bracketing algorithm
  • Also works well in F# with the F# extensions.
• Linear Algebra:
  • Native eigenvalue decomposition (EVD) support with our MKL packages ~Marcus Cuda
  • Add missing scalar-vector operations (s-v, s/v, s%v) ~Thomas Ibel
  • Support for new F# 3.1 row/column slicing syntax on matrices
  • Matrices learned proper OfColumn/RowVectors, analog also in F#.
  • Documentation Fixes ~Robin Neatherway
  • BUG: Fixed exception text message when creating a matrix from enumerables (rows vs columns) ~Thomas Ibel
  • We're phasing out MathNet.Numerics.IO that used to be included in the main package for matrix file I/O for text and Matlab formats. Use the new .Data.Text and .Data.Matlab packages instead.
• Statistics: Spearman Rank Correlation Coefficient ~Iain McDonald
• Statistics: Covariance function, in Array-, Streaming- and common Statistics.
• Distributions: Categorical: distribution more consistent, no longer requires normalized pdf/cdf parameters
• Distributions: Categorical: inverse CDF function ~Paul Varkey
• BUG: Distributions: Fixed static sampling methods of the Stable distribution. ~Artyom Baranovskiy
• BUG: Fixed a bug in the Gamma Regularized special function where in some cases with large values it returned 1 instead of 0 and vice versa.
• The F# extensions now have a strong name in (and only in) the signed package as well (previously had not been signed). ~Gauthier Segay
• Evaluate.Polynomial with new overload which is easier to use.
• Fixed a couple badly designed unit tests that failed on Mono.
• Repository now Vagrant-ready for easy testing against recent Mono on Debian.

2.5.0 - 2013-04-14

• See also: What's New in Math.NET Numerics 2.5
• Statistics: Empty statistics now return NaN instead of either 0 or throwing an exception. This may break code in case you relied upon the previous unusual and inconsistent behavior.
• Linear Algebra: More reasonable ToString behavior for matrices and vectors. This may break code if you relied upon ToString to export your full data to text form intended to be parsed again later. Note that the classes in the MathNet.Numerics.IO library are more appropriate for storing and loading data.
• Statistics:
  • More consistent behavior for empty and single-element data sets: Min, Max, Mean, Variance, Standard Deviation etc. no longer throw exceptions if the data set is empty but instead return NaN. Variance and Standard Deviation will also return NaN if the set contains only a single entry. Population Variance and Population Standard Deviation will return 0 in this case.
  • Reworked order statistics (Quantile, Quartile, Percentile, IQR, Fivenum, etc.), now much easier to use and supporting compatibility with all 9 R-types, Excel and Mathematica. The obsolete Percentile class now leverages the new order statistics, fixing a range check bug as side effect.
  • New Hybrid Monte Carlo sampler for multivariate distributions. ~manyue
  • New financial statistics: absolute risk and return measures. ~Phil Cleveland
  • Explicit statistics for sorted arrays, unsorted arrays and sequences/streams. Faster algorithms on sorted data, also avoids multiple enumerations.
  • Some statistics like Quantile or empirical inverse CDF can optionally return a parametric function when multiple evaluations are needed, like for plotting.
• Linear Algebra:
  • More reasonable ToString behavior for matrices and vectors: ToString methods no longer render the whole structure to a string for large data, among others because they used to wreak havoc in debugging and interactive scenarios like F# FSI. Instead, ToString now only renders an excerpt of the data, together with a line about dimension, type and in case of sparse data a sparseness indicator. The intention is to give a good idea about the data in a visually useful way. How much data is shown can be adjusted in the Control class. See also ToTypeString and ToVector/MatrixString.
  • Performance: reworked and tuned common parallelization. Some operations are up to 3 magnitudes faster in some extreme cases. Replaced copy loops with native routines. More algorithms are storage-aware (and should thus perform better especially on sparse data). ~Thomas Ibel, Iain McDonald, Marcus Cuda
  • Fixed range checks in the Thin-QR decomposition. ~Marcus Cuda
  • BUG: Fixed bug in Gram Schmidt for solving tall matrices. ~Marcus Cuda
  • Vectors now implement the BCL IList interfaces (fixed-length) for better integration with existing .NET code. ~Scott Stephens
  • Matrix/Vector parsing has been updated to be able to parse the new visual format as well (see ToMatrixString).
  • DebuggerDisplay attributes for matrices and vectors.
  • Map/IndexedMap combinators with storage-aware and partially parallelized implementations for both dense and sparse data.
  • Reworked Matrix/Vector construction from arrays, enumerables, indexed enumerables, nested enumerables or by providing an init function/lambda. Non-obsolete constructors now always use the raw data array directly without copying, while static functions always return a matrix/vector independent of the provided data source.
  • F#: Improved extensions for matrix and vector construction: create, zeroCreate, randomCreate, init, ofArray2, ofRows/ofRowsList, ofColumns/ofColumnsList, ofSeqi/Listi (indexed). Storage-aware for performance.
  • F#: Updated map/mapi and other combinators to leverage core implementation, added -nz variants where zero-values may be skipped (relevant mostly for sparse matrices).
  • F#: Idiomatic slice setters for sub-matrices and sub-vectors
  • F#: More examples for matrix/vector creation and linear regression in the F# Sample-package.
• Control: Simpler usage with new static ConfigureAuto and ConfigureSingleThread methods. Resolved misleading configuration logic and naming around disabling parallelization.
• Control: New settings for linear algebra ToString behavior.
• Fixed range check in the Xor-shift pseudo-RNG.
• Parallelization: Reworked our common logic to avoid expensive lambda calls in inner loops. Tunable.
• F#: Examples (and thus the NuGet Sample package) are now F# scripts prepared for experimenting interactively in FSI, instead of normal F# files. Tries to get the assembly references right for most users, both within the Math.NET Numerics solution and the NuGet package.
• Various minor improvements on consistency, performance, tests, xml docs, obsolete attributes, redundant code, argument checks, resources, cleanup, nuget, etc.

2.4.0 - 2013-02-03

• Adds Modified Bessel & Struve special functions ~Wei Wu
• BUG: Fixes a bug in our iterative kurtosis statistics formula ~Artyom Baranovskiy

• Linear Algebra: Simplifications around using native linear algebra providers (see Math.NET Numerics With Native Linear Algebra)
• F#: Adds the BigRational module from the F# PowerPack, now to be maintained here instead. ~Gustavo Guerra
