In aninitial value problem, the ODE is solved by starting from an initial state. Using the initial condition,y0, as well as a period of time over which the answer is to be obtained,(t0,tf), the solution is obtained iteratively. At each step the solver applies a particular algorithm to...

Convert a system of symbolic differential algebraic equations to a function handle suitable for the MATLAB ODE solvers. Then solve the system by using theode15ssolver. Create the following second-order differential algebraic equation. syms y(t); ...
ode23s(stiff differential equation solver)是MATLAB中的一种求解刚性(stiff)微分方程的数值方法。刚性微分方程通常具有多个时间尺度差异较大的变量,并且其中至少有一个变量具有快速变化的特性。 ode23s方法使用了一个隐式的一步法(implicit one-step method),结合了 Rosenbrock 方法和 backward differentiation formula (...
The latter is closely related to the solver used by the simulation environment and plays an essential role in evaluating the quality of the simulation process. In this study, the performances of some solvers used in MATLAB, SIMULINK, and SIMSCAPE MULTIBODY environments are investigated and ...

Simple ODEs that have a single solution component can be specified as an anonymous function in the call to the solver. The anonymous function must accept two inputs(t,y), even if one of the inputs is not used in the function.
At each step, the ODE solver estimates the local error e in the ith component of the solution. To be successful, the step must have acceptable error, as determined by both the relative and absolute error tolerances: |e(i)| <= max(RelTol*abs(y(i)),AbsTol(i)) Example: opts = odeset...
