Cell input to ode45 function
显示 更早的评论
Hey Folks!
Please help me out with the problem below.
I've been trying to run a ode45 function that simulates 4 variables simulataneously. one among the 4, by itself has 7 variables inside it.
Like supposed say, I need to simulate this cell, y = {X(t),S(t),P(t),V(t)} where X,P & V are doubles. And S is a vector with values for 7 variables.
i.e. S(t) = [s1(t),s2(t),..,s7(t)].
So, is it by any means possible for me to simulate as below?
y0 = {X(t),S(t),P(t),V(t)} % Initial conditions
[t,y] = ode45(dydt, tspan, y0}
where the resulting "y" is cell output.

You can take all variables as an vector instead of cell array. For example,
y = [X(t), S_1(t), ... S_7(t), P(t), V(t)]'.
Then you need to define dydt accordingly.
ode45 does not support cell input.
