`ndarray-linear-interpolate` is a tiny Node.js library that performs multilinear (bilinear, trilinear, etc.) interpolation on arbitrary‑dimensional `ndarray` data structures. It exports a simple function (and fast 1‑, 2‑, and 3‑dimensional shortcuts) that takes an ndarray and continuous coordinates and returns the interpolated value, making it useful for scientific, graphics, or signal‑processing code that works with grid‑based numeric data.
