Authors	Franck Djeumou, Abraham P. Vinod, Eric Goubault, Sylvie Putot, and Ufuk Topcu
Conference	American Control Conference, 2021

Disclaimer: The code is provided as-is, no updates expected. A new and complete version of DaTaReach and DaTaControl (data-driven algorithms to over-approximate the reachable set and control unknown systems, respectively) based on recent results will be upload soon.

This repository provides codes to reproduce the experiments and figures of the paper.

Construction of data-driven differential inclusions and computation of over-approximations of the reachable set of dynamics described by the differential inclusions.
