chdh/commons-math-interpolation

This TypeScript package provides interpolation algorithms, including Akima cubic spline, natural cubic spline, linear, and nearest neighbor interpolation, as well as LOESS/LOWESS local regression. It's a partial port of the Apache Commons Math library, designed for developers working with TypeScript who need robust interpolation functionality for datasets of x/y points. The package includes interactive demos and is available on NPM for easy integration into projects.
