Abstract

We present OURS, a precision-oriented MATLAB tool for computing ver- and nder- approximations of eachable ets for analytic time-invariant differential equations. The main theoretical framework behind OURS is introduced, including the concept of evolution function, whose zero sub-level sets are used to describe reachable sets, and a series representation of evolution function. Using the partial sums of this series, OURS finds over- and under-approximations of evolution function at time-instants: it consecutively estimates each remainder of the corresponding partial sum of the series with interval arithmetics until one remainder satisfies the designated precision, and then builds over- and under-approximations with this remainder. The structure of OURS is also presented, such as the forms of inputs and outputs, and technical implementations of the crucial steps inside. We also compare OURS with two other existing methods.
