# 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.

This textbook introduces several major numerical methods for solving various partial differential equations (PDEs) in science and engineering, including elliptic,
