Now I solve the differential equations for zero initial conditions via Runge-Kutta (as in Code file). As a result I come to 6 time-dependent solutions which are plotted when running the file Code.

This example shows you how to convert a second-order differential equation into a system of differential equations that can be solved using the numerical solver ode45 of MATLAB®. 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.

Matlab solve system of differential equations numerically

When solving a system of equations, always assign the result to output arguments. Output arguments let you access the values of the solutions of a system. This example shows you how to convert a second-order differential equation into a system of differential equations that can be solved using the numerical solver ode45 of MATLAB®. 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. This example shows you how to convert a second-order differential equation into a system of differential equations that can be solved using the numerical solver ode45 of MATLAB®.

Matlab solve system of differential equations numerically

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. Differential equation or system of equations, specified as a symbolic equation or a vector of symbolic equations. Specify a differential equation by using the == operator. If eqn is a symbolic expression (without the right side), the solver assumes that the right side is 0, and solves the equation eqn == 0 . How to solve the differential equation numerically.
