Hi,
How can i solve a system of nonlinear differential equations using Matlab?? here is an example of what i'm talking about it's not the problem that i'm working in but it had the same form. //// x'=3x+y//// y'=y-x+y^4+z^4//// z'=y+z^4+y^4+3/// the ' means the derivative. i'll appreciate your help, best regards!

eg for your case
f1 = @(t,y)[3*y(1)+y(2);y(2)-y(1)+y(2).^4+y(3).^4;y(2)+y(2).^4+y(3).^4+3]
[T,Y] = ode45(f1,[0 .1],zeros(3,1))

how about using other methods to solve this example ? such as Euler method and Midpoint method. Could you solve it?

Hi how can i solve the following equation 2f"'-(f')^2+f”-f’=0 f(0)=0, f’(0)=0 by using MAT lab
note: the ' means the derivative

Hello!!!
How i can solve this equaion?
y'(t)=-y(t)+e^tauy(t-tau)g(x(t-tau))
