Lyo.Mathematics

C# contracts for the Lyo math stack: physical quantities as structs, 2D/3D vectors and small matrices, typed inputs/results for formulas, and a small registry so they can be discovered. Numerical implementations live in Lyo.Mathematics.Functions (F#).

Target frameworks: netstandard2.0, net10.0

Folders and namespaces

Area Namespace Purpose
Quantities Lyo.Mathematics.Quantities Strongly typed SI-oriented values (mass, length, angles, …) with operators and factory methods.
Vectors Lyo.Mathematics.Vectors Vector3D, Vector2D. Normalize, magnitude, cross/dot (3D), angles, projections.
Matrices Lyo.Mathematics.Matrices Matrix3x3, Matrix2x2. Element storage for linear algebra functions.
Models Lyo.Mathematics.Models DTO-style struct/record inputs and results for calculus, statistics, finance, physics, etc.
Unit enums Lyo.Mathematics.Units MassUnit, LengthUnit, TimeUnit, AngleUnit for conversions or display where used.
Registry Lyo.Mathematics.Registry FormulaDescriptor, MathematicsFormulaRegistry. Curated ids for docs or UIs.
(root) Lyo.Mathematics MathematicsWorkflowExtensions. A few C# convenience extensions.

Internal helpers (MathValueGuards, MathematicsDisplayFormat) support consistent ToString() and finite/non-negative validation on quantity constructors.

Quantities (Lyo.Mathematics.Quantities)

Most quantities are readonly record struct types holding a canonical SI scalar (e.g. kilograms, meters) plus From* factories, common derived accessors, and arithmetic where meaningful. Non-finite or out-of-range values throw via MathValueGuards / ArgumentHelpers as documented per type.
