Release of NMath 7.2

NMath version 7.2 has been released and includes the following packages:

• CenterSpace.NMath.Standard.Windows.X64
• CenterSpace.NMath.Standard.Linux.X64
• CenterSpace.NMath.Standard.OSX.X64
• CenterSpace.NMath.Charting.Framework.Windows.X64

This version requires developers to be using at least .NET Core 2.0 or at least .NET Framework 4.6.1. Adding support of .NET Core to NMath has been in the works for over a year and was done at the request of many of our active developers.

Future development work will concentrate on the .NET Standard based NMath 7.0. However, NMath 6.2, build on .NET 4.0, but not supporting the .NET Standard Library, will be available for years to come.

Below is a list of major changes released in NMath 7.0:

• 32-bit support has been dropped. Demand has been waning for years for this. Dropping it has made usage simpler and easier.
• GPU support has been dropped. As developers, we liked the automatic GPU offloading. However, the technical advantages have dissipated as multi-core processors have improved. We believe that this is no longer compelling for a general math library.
• NMath Stats has been merged into NMath. This is for ease of use for our users.
• In summer of 2019, our pricing will be streamlined to reflect these changes. There will be one price for a perpetual NMath license and there will be one price for annual NMath maintenance which includes technical support and all upgrades available on NuGet. NMath Stats will no longer be sold separately.
• We have merged the four NMath namespaces into one, CenterSpace.NMath.Core, to simplify development. Originally, CenterSpace had four NMath products and four namespaces, these namespaces CenterSpace.NMath.Core, CenterSpace.NMath.Matrix, CenterSpace.NMath.Stats, CenterSpace.NMath.Analysis reflect that history. We have left stubs so users won’t have any breaking changes.
• We have dropped charting. The ecosystem is full of powerful visualization packages. We have only three main data structures in NMath, vectors, matrices and data frames, and all can be easily used with different charting packages.
• Some of our optimizations use Microsoft Solver Foundation. If you use these, you’ll need to be on the .NET Framework track and not on the .NET Core track.
• We have dropped the installers. The compelling ease of NuGet for our users has made these obsolete.

Added functionality includes:

• Upgraded to Intel MKL 11.3 Update 2 with resulting performance increases.
• Updated NMath Premium GPU code to CUDA 7.5.
• Added classes for performing Discrete Wavelet Transforms (DWTs) using most common wavelet families, including Harr, Daubechies, Symlet, Best Localized, and Coiflet.
• Added classes for solving stiff ordinary differential equations. The algorithm uses higher order methods and smaller step size when the solution varies rapidly.
• Added classes for performing two-way ANOVA with unbalanced designs.
• Added classes for performing Partial Least Squares Discriminant Analysis (PLS-DA), a variant of PLS used when the response variable is categorical.

Upgrades are provided free of charge to customers with current annual maintenance contracts. To request an upgrade, please visit our upgrade page, or contact sales@centerspace.net. Maintenance contracts are available through our webstore.

The post Announcing NMath 6.2 and NMath Stats 4.2 appeared first on CenterSpace.

NMath Core, NMath Matrix and NMath Analysis have been merged into one product — NMath. This will simplify inter-library dependencies. For backward compatibility, the namespaces will be unchanged.
