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

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?

If you have the symbolic toolbox then
dsolve('Dy=2*x*y', 'x')

... 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."
