@@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...

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
