Remarks
The Interpolation class provides a set of static methods for fast, single-point evaluation of common interpolation schemes. These methods operate directly on arrays and perform no allocations, making them suitable for performance-critical scenarios where a reusable curve object is not needed.
For scenarios requiring repeated evaluation, resampling, or additional operations like differentiation and integration, use the curve generator factory methods that return concrete curve types from the Numerics.NET.Curves namespace.
