The system. Consider the nonlinear system. dsolve can't solve this system. I need to use ode45 so I have to specify an initial value. Solution using ode45. This is the three dimensional analogue of Section 14.3.3 in Differential Equations with …
A second problem is that, even if you were to be able to run the function like this, ode45 would call the function example, which would call ode45, which would call example, which would call ode45 and so on, until the recursion limit is reached. The solution to both is to split it up in two functions (these may be written into the same M-file):

26.05.2016 · The ode45 function within MATLAB uses the Dormand-Prince formulation. To understand the input parameters for the ode45 function, type “doc ode45” and “doc odeset” in the MATLAB command window. Now Let’s Get Started. For this problem, the equation of motion for the satellite will be coded as an anonymous function.
This technique creates a system of independent equations through scalar expansion, one for each initial value, and ode45 solves the system to produce results for each initial value. Create an anonymous function to represent the equation f ( t, y) = - 2 y + 2 cos ( t) sin ( 2 t). The function must accept two inputs for t and y.
1 Solving Systems of Differential Equations. We know how to use ode45 to solve a first order differential equation, but it can handle much more than this.
