  • Description
  • Ellipsoidal Toolbox is a standalone set of
    easy-to-use configurable MATLAB routines to
    perform operations with ellipsoids and
    hyperplanes of arbitrary dimensions. It computes
    the external and internal ellipsoidal
    approximations of geometric (Minkowski) sums and
    differences of ellipsoids, intersections of
    ellipsoids and intersections of ellipsoids with
    halfspaces and polytopes distances between
    ellipsoids, between ellipsoids and hyperplanes,
    between ellipsoids and polytopes and projections
    onto given subspaces.
  • Ellipsoidal methods are used to compute forward
    and backward reach sets of continuous- and
    discrete-time piecewise affine systems. Forward
    and backward reach sets can be also computed for
    continuous-time piece-wise linear systems with
    disturbances. It can be verified if computed
    reach sets intersect with given ellipsoids,
    hyperplanes, or polytopes
