Approximating the real structured distance to instability.
Approximating the real structured distance to defectivity.
  • The compressed folder dtdef.zip contains a directory with the Matlab routines for approximating the distance from above.
Delay Differential Equations
For nonstiff problems
  • RETARD Extension of the code DOPRI5 to delay differential equations y'(t)=f(t,y(t),y(t-a),...)
  • DR_RETARD Driver for RETARD
For stiff problems, including differential-algebraic and neutral delay equations with constant or state-dependent (eventually vanishing) delay.
  • the tar file radar5-v2.1.tar contains a directory with the Fortran 90 code RADAR5, the necessary linear algebra routines, and subdirectories for the following eleven examples. For unfolding the directory use the command tar xvf radar5-v2.1.tar
