Need a column vector from ode45, but I keep getting a struct
显示 更早的评论
For some homework I'm trying to use ODE45 using a third-order chemical reaction equation.
k3 = 0.1;
tspan = 0:100;
C0 = 0.6;
dCadt = @(t,Ca) (-k3.*Ca.^3);
ode_solver = ode45(dCadt, tspan, C0); % ODE solver used in task 3, using the formula from Q1
this is the code I'm using, but I keep getting a struct and I can't extract any values from that. I would like to get a column vector, so I can calculate errors between different ODE solvers. Can anyone help me with this?

Read about structures.
k3 = 0.1;
tspan = 0:100;
C0 = 0.6;
dCadt = @(t,Ca) (-k3.*Ca.^3);
ode_solver = ode45(dCadt, tspan, C0); % ODE solver used in task 3, using the formula from Q1
plot(ode_solver.x,ode_solver.y)

Command
[T, Ca] = ode45(dCadt, tspan, C0);
should be easier to work with.
