Solve numerically matlab

WebA typical approach to solving higher-order ordinary differential equations is to convert them to systems of first-order differential equations, and then solve those systems. The example uses Symbolic Math Toolbox™ to convert a second-order ODE to a system of first-order ODEs. Then it uses the MATLAB solver ode45 to solve the system.
