  DDEBIFTOOL is a collection of Matlab routines for numerical bifurcation
analysis of systems of delay differential equations with discrete constant and
state-dependent delays. The package supports continuation and stability
analysis of steady state solutions and periodic solutions. Further one can
compute and continue several local and global bifurcations: fold and Hopf
bifurcations of steady states; folds, period doublings and torus bifurcations
of periodic orbits; and connecting orbits between equilibria. To analyse the
stability of steady state solutions, approximations are computed to the
rightmost, stability-determining roots of the characteristic equation which can
subsequently be used as starting values in a Newton procedure. For periodic
solutions, approximations to the Floquet multipliers are computed. The manual
describes the structure of the package, its routines, and its data and method
parameter structures.
