hi all,

I am solving a set of ODE (non-linear) here is first (this one is linear but i need to solve this concept before moving on).

f2 = @(t,X) [a*X(1)];

a is a number.

[t,y] = ode45(f2,[0 : t],[1]);

how can i set up the code so that the it stops at time t when a certain value in y has been reached. Then a new ODE comes into play.

thanks everyone - much appreciated.
