Delay Differential Equations - MATLAB & Simulink
https://www.mathworks.com/help/matlab/delay-differential-equations.html
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 …
