Module spline_eval 

Public spline evaluation helpers for generated density function code.

These operate on raw data (slices, scalars) rather than the CubicSpline struct, so generated code can call them with statically embedded spline data.

Functions

evaluate_spline

Evaluate a spline defined by static data arrays.

find_interval

Binary search to find the interval start: largest i where locations[i] <= input.

hermite_interpolate

Hermite cubic interpolation between two adjacent spline points.
