Dew.Math.Core
Dew.Math.Core is the portable, pure managed edition of the Dew.Math library. It provides the same high-level matrix and vector programming model, expression parser, probability and optimization toolkit, and special function support without linking to any native runtime components. This enables maximum compatibility across platforms and runtime environments. Core Numerical Capabilities (Managed): - Dense matrix and vector operations with operator overloading and method-based APIs - QR, LU, SVD and eigenvalue routines using high-quality managed linear algebra kernels - Complex number and real-valued computation with full vectorization in managed code - Sparse matrix representations with iterative solver support - Probability distributions, histogramming, random generators, Monte Carlo workflows - Nonlinear optimization, curve fitting, regression models, trust-region and gradient methods - Vectorized expression parsing for symbolic-style expression and simulation pipelines - Polynomial and spline interpolation, numerical integration and differentiation - Special function suite including Bessel, Airy, Gamma-related, Legendre and elliptic functions Portability Model: - No native libraries required (zero unmanaged dependencies) - Runs on Windows, Linux, macOS, iOS, Android, MAUI, Uno, WASM, Unity*, cloud functions and plugins - Targets netstandard2.0, net8.0, and net9.0 Use Dew.Math.Core when you need **maximum portability** in libraries, shared simulation engines, tooling, mobile deployments, WebAssembly environments, or plugin architectures.
Dew.Math.Core
Cross-platform managed math library for .NET
Dew.Math.Core is the portable, pure managed edition of the Dew.Math library. It provides the same high-level vector and matrix programming model, expression parser, probability and optimization toolkits, and special function support, but does not rely on any native runtime libraries. This enables maximum compatibility across platforms and deployment environments.
Use Dew.Math.Core when building applications and shared libraries that must run on Windows, Linux, macOS, iOS, Android, MAUI, Uno, WebAssembly, Unity* and containerized or plugin-based systems without requiring platform-specific native dependencies.
Key Features
- Same programming model as Dew.Math: Vectors, Matrices, subranges, views and capacity-based memory design
- Pure managed implementation (no native BLAS, LAPACK or external libraries required)
- Operator overloads and method-based APIs for vectorized computation
- Complex number support throughout the vector and matrix system
- Expression parser and vectorized formula evaluation
Optimization and Curve Fitting
Includes nonlinear optimization methods:
- Simplex (Nelder-Mead)
- Marquardt (with numerical derivatives)
- BFGS
- Conjugate Gradient
- Trust Region
Probability and Special Functions
- Probability distributions and random number generators
- Monte Carlo workflows
- Polynomial tools, spline interpolation, piecewise functions and polynomial fitting
- Numerical differentiation and integration routines
- Special mathematical functions including: Airy, Bessel, Gamma-related families, Legendre polynomials, elliptic integrals
Advanced Memory Model
The same advanced memory and concurrency design from Dew.Math is also available in Dew.Math.Core:
- Vectors and Matrices expose a Capacity property to reduce allocation count
- Subranges (views / spans) allow memory partitioning without copying
- Object pool enables parallel allocation with minimal GC pressure
- Designed for multi-threading from the start (MtxVec lineage)
- Nearly all math operations avoid internal allocations
This makes Dew.Math.Core suitable for long-running simulation engines, model servers, and streaming computation pipelines where predictable allocation patterns matter.
Platform and Deployment Model
- No native libraries required (pure managed)
- Works on:
- Windows
- Linux
- macOS
- iOS / Android (via Xamarin / MAUI)
- Uno, Avalonia, Blazor / WebAssembly
- Unity* (subject to IL2CPP/AOT constraints)
Target Frameworks
- netstandard2.0
- net8.0
- net9.0
Drop-in Replaceable Architecture (Important)
Dew.Math.Core shares the same namespaces and class names as:
- Dew.Math (Windows hardware-accelerated)
- Dew.Math.Linux (Linux hardware-accelerated)
This allows switching editions without modifying code.
Example deployment workflow:
- Develop on Windows using Dew.Math.Core (maximum portability)
- Before final deployment:
- Replace Dew.Math.Core with Dew.Math for Windows acceleration, or
- Replace Dew.Math.Core with Dew.Math.Linux for Linux acceleration
- Rebuild your solution. No source changes required.
No #ifdef, no dual code paths, no API differences.
Hardware-Accelerated Editions (Optional)
| Package | Platform | Acceleration Model |
|---|---|---|
| Dew.Math | Windows | Native AVX2 / AVX-512 acceleration |
| Dew.Math.Linux | Linux | Native AVX2 / AVX-512 acceleration |
| Dew.Math.Core | All | Managed-only, portable |
