Web[t,y,te,ye,ie] = ode15s(odefun,tspan,y0,options) additionally finds where functions of (t,y), called event functions, are zero. In the output, te is the time of the event, ye is the solution at the time of the event, and ie is the index of the triggered event. For each event function, specify whether the integration is to terminate at a zero and whether the direction of the … WebMar 11, 2024 · 例如，假设要解决如下微分方程： ``` dy/dt = -2*y + 4*t ``` 可以定义如下函数： ```python def myode(y, t): dydt = -2*y + 4*t return dydt ``` 接下来，需要指定初值和时间范围： ```python y0 = 1.0 # 初始状态变量的值 t = np.linspace(0, 5, 101) # 时间范围，从0到5，共101个点 ``` 最后，可以使用odeint函数解方程： ```python sol ...
