CAPD DynSys Library  5.2.0
The capdDynSys package

The capdDynSys package contains modules that was originally intended for rigorous computations in dynamical systems but currently they are go far beyond this. It consist of the following modules:

  • map - computation of values and derivatives of maps. It is also the core for the solvers in dynsys module,
  • dynsys - various nonrigorous and rigorous solvers to ODEs, for computations of the solutions and partial derivatives w.r.t. initial conditions up to arbitrary order,
  • geomset, dynset - various representations of sets and Lohner-type algorithms,
  • poincare - computation of Poincare maps and their derivatives; both rigorous and nonrigorous,
  • diffIncl - rigorous computations of the solutions to differential inclusions,
  • newton - utils related to interval Newton and Krawczyk method,
  • covrel - h-set representations and methods for checking covering relations,
  • normalForms - operations on Taylor series and routines for normal forms of a planar map
