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. Solve this system of linear first-order differential equations. d u d t = 3 u + 4 v, d v d t = − 4 u + 3 v. First, represent u and v by using syms to create the symbolic functions u (t) and v (t). syms u (t) v (t) Define the equations using == and represent differentiation using the diff function.

In the equation, represent differentiation by using diff Use MATLAB to numerically solve a first order ordinary differential equation (ODE) for time t = 0s tot = 10s. * + x = 0 *(0) = 0.1 To do this, we first re-write our ODE as * = -x In MATLAB, open the editor type the following code to (1) define the time vector and initial conditions, (2) solve a differential equation using ODE45, and (3 Solve a System of Differential Equations.

What you are outlining in your question (parallel) are so-called coupled differential equations. x1 and x2 - or rather, their time derivatives - are functions of each other. The only way to solve these kinds of equations is by solving them, as you said, in parallel. And that's accomplished in MATLAB by using e.g. ode45.

I have below system of equations. Is it possible to solve this with ode45 of matlab? I know that I need to convert the second order equations to two first order ones, but my confusion comes from the term which is the product of derivatives of s and theta.
