Build financial, engineering and scientific applications faster
Numerics.NET (formerly Extreme Optimization Numerical Libraries for .NET) is a collection of general-purpose mathematical and statistical classes built for Microsoft .NET.
Numerics.NET provides the first complete platform for technical and statistical computing built on and for the Microsoft .NET platform. It combines a math library, a vector and matrix library, a data analysis library, and a statistics library in one convenient package.
At a glance:
Mathematics
- Seamless parallelism using the Task Parallel Library.
- Basic math: Complex numbers,
