You first need to convert this function into a form, which can be passed in ode45
To solve using ode45, you need to have three important inputs -> @equation, timerange, initial condition, options
hence your equation should begin like:
function X2d = dynamics(t, Y, options):
Y contains all the initial conditions of the variables.
options contain the arguements that you might need to pass in.
define the constants inside the function.
Then proceed with your code.
Good luck.
