MatLAB 中解时滞微分方程 怎么写?MatLAB中解时滞微分方程sol=dde23(ddefun

这是matlab中dde23的例子,通过这个例子,应该能看懂dde23个参数的作用.直接复制后边的代码就可以输出图形.%DDEX1 Example 1 for DDE23.% This is a simple example of Wille' and Baker that illustrates the% straightforward formulation,computation,and plotting of the solution % of a system of delay differential equations (DDEs).%% The differential equations%% y'_1(t) = y_1(t-1) % y'_2(t) = y_1(t-1)+y_2(t-0.2)% y'_3(t) = y_2(t)%% are solved on [0,5] with history y_1(t) = 1,y_2(t) = 1,y_3(t) = 1 for% t

谢谢了
