This helped me understand how to work with a system of four odes. Thanks !

Really nice video! Great work buddy!

Sir if i have two functions in same equation like f and g ...how to use ode45 to plot graph...pls help me...
My equation is
f'''-2(f'+g')f'+(f+g)f''-Mf'=0
BC f(0)=0 f'(0)=1 g(0)=0 g'(0)=0.3
M=0.5

Hi..thanks for this video..I have 2 nonlinear coupled equations that should be solved using ode..but I have problem doing that..can I ask for your help please..?

Hi Ghazal, can you write your equations in the comment, I may be able to assist.

​@@JoseGutierrez-vp7oc Hello Jose, I also need some help with ode Solver. Its about a Newton's Cradle with only two balls, wich i have to solve with ode. I could so far only determine the equations :
%Initial Conditions
r = 0.05; % Radius beider Kugeln
l = 0.3; % Seillänge
m_rechts = 50; % Masse der rechten Kugel
m_links = 50; % Masse der linken Kugel
phi_rechts_initial = pi/3;
phidot_rechts_initial =0;
phi_links_initial = 0;
phidot_links_initial =0;
J_rechts = (m_rechts*l^2);
J_links = (m_links*l^2);
ts = 0.001;
timespan = 0:ts:40;
g = 9.81;
phi_ddot_links = -(m_links*g*sin(phi_links*l))/ J_links;
phi_dot_links = phi_dot_links + phi_ddot_links * ts;
phi_links = phi_links + phi_dot_links * ts;

phi_dot_links_neu = 2*(J_links*phi_dot_links+J_rechts*phi_dot_rechts)/(J_links+J_rechts) - phi_dot_links;
phi_dot_rechts_neu = 2*(J_links*phi_dot_links+J_rechts*phi_dot_rechts)/(J_links+J_rechts) - phi_dot_rechts;
Can you help me to solve this issue...

how would i able to solve the tunnel diode state space variable using ode 45, bcuz i dont have the initial value or the experental value

Great! Thank you so much!

We find it very difficult to follow up what is on the screen when you turn on the text repeating what you are you are saying on the screen .
