Using loops for an initial condition change

1 次查看(过去 30 天)
I am using ode45 to solve a set of differentials. At a particular point in the timespan the conditions need to be set to a fixed value, and the solver restarted to continue to solve.
For example, at time = 24 the y0 must change an be reinstated as the initial value with the ode45 solving from this point onwards.
t = [0 6 12 18 24 30 36 42 48];
y0 = [16; 0.5; 0; 2; 0; 0; 0; 0; 0.25];
[t, y] = ode45 (@solver, t ,y0);

Break it up into two callsz one with timespan ending at that time, and the second starting from that time. Copy the end boundary conditions from the first call, make any necessary adjustments to that, and pass that in to the second call as the initial conditions.
