Delay Differential Equations
Delay differential equations contain terms whose value depends on the solution at prior times. The time delays can be constant, time-dependent, or state-dependent, and the choice of the solver function (dde23
, ddesd
, or ddensd
) depends on the type of delays in the equation. Typically the time delay relates the current value of the derivative to the value of the solution at some prior time, but in the case of a neutral equation it can depend on the value of the derivative at prior times. Since the equations depend on the solution at prior times, it is necessary to provide a history function that conveys the value of the solution before the initial time t0.
