The equation is written as a system of two first-order ordinary differential equations (ODEs). These equations are evaluated for different values of the parameter μ.For faster integration, you should choose an appropriate solver based on the value of μ.. For μ = 1, any of the MATLAB ODE solvers can solve the van der Pol equation efficiently.The ode45 solver is one such example.

Choose an ODE Solver Ordinary Differential Equations. An ordinary differential equation (ODE) contains one or more derivatives of a dependent variable, y, with respect to a single independent variable, t, usually referred to as time.The notation used here for representing derivatives of y with respect to t is y ' for a first derivative, y ' ' for a second derivative, and so on.

Higher order differential equations must be reformulated into a system of first order differential equations. Note! Different notation is used:!"!# = "(= "̇ Not all differential equations can be solved by the same technique, so MATLAB offers lots of different ODE solvers for solving differential equations, such as ode45, ode23, ode113, etc.
