It also lets the user choose what termination criterion to use, either a specified x value or a number ...Aug 20, 2020 · MATLAB有很多用于求解微分方程的内置功能。MATLAB包含了用于求解常微分方程（ODE）的函数 高阶微分方程必须重新表述为一个一阶系统微分方程。并不是所有的微分方程都可以用同样的方法求解，所以MATLAB提供了许多不同的常微分方程求解器，如ode45、ode23、ode113等。

EDIT 2. Seems that MATLAB's Symbolit Toolbox can't handle differentiation with respect to q(t), so you have to use the variable q.. So using these as functions. q ...The Forward Euler Method is the conceptually simplest method for solving the initial-value problem. For simplicity, let us discretize time, with equal spacings: t0, t1, t2, … where h ≡ tn + 1 − tn. Let us denote →yn ≡ →y(tn). The Forward Euler Method consists of the approximation. →yn + 1 = →yn + h→F(→yn, tn).
