Lorentz Integrator Numerical Simulation

I need a bit of help to develop a numerical simulation to integrate the Lorentz force equation. These are some of the parameter I was given:

x0 = [0, 0, 0]

v0 = [0, 1, 0]

q = 1, m = 1

B = [0, 0, 10]; Magnetic Field

E = [0, 0, 0] Electric Field

n = 500: number of time steps

dt = 0.01: time step

I am supposed to use ode45 to solve 6 first order differential equations and plot the solution in a 3D plot. Not sure how to go about this.

It would be better if you show what you did so far. What you tried, where you are not sure and which part did you not understand. Otherwise this is a "do it for me" type of question and it is highly unlikely for someone to do it for you.

I'm pretty new to matlab so I'm not really sure how to start. I just need someone to point me in the right direction on how to go about it. I don't need the problem done for me
