## Overview

This is a small MATLAB repository described as a velocity prediction program for analysing Moth performance. The tree shows boat and environment parameter modules plus a rudder module, but no main entry point or source excerpts, so their wiring and any broader performance-calculation workflow cannot be established. The graph therefore limits itself to the documented product purpose and the modules evidenced by filenames.
