A 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.x = lsqr (A,b) attempts to solve the system of linear equations A*x = b for x using the Least Squares Method . lsqr finds a least squares solution for x that minimizes norm (b-A*x). When A is consistent, the least squares solution is also a solution of the linear system. When the attempt is successful, lsqr displays a message to confirm ...
