Solve the differential equation numerically using matlab

dy/dx=2xy

Answer 1

[Torsten]

fun=@(t,y)2*t*y;
Tspan = [0 2]; 
y0=1;
[T,Y] = ode45(fun,Tspan,y0);
plot(T,Y(:,1));

Thank you sir. but i am a beginner,have an alternative methods for this ?

[Walter Roberson]

That is the beginner version.

Are you asking for the "beginner" version, or are you asking for the homework version in which you need to calculate it without using the ode functions?

[Ahamed Zajith]

thank you, i need a code without using ode function sir

[Walter Roberson]

If you have the symbolic toolbox then

dsolve('Dy=2*x*y', 'x')

[Ahamed Zajith]

its great.Thank you sir.

[Torsten]

... but this is not a numerical solution.

For some reason what runs through my mind is the classic, "So nail it to a wall then."
