Question about printing ode45 results

Hello everyone. I have recieved a code in which an expression is called as [t, x]=ode45(@(t,x) example(t,x),tspan,x0); inside of it I have three vectors called u1d, u2d and u3d. I also have

u(1)=interp1(time,u1d,t,'linear');
u(2)=interp1(time,u2d,t,'linear');
u(3)=interp1(time,u3d,t,'linear');

I want to compare u(1) with u1d, u(2) with u2d and u(2) with u3d to see how good the interpolation is. The problem is that if I write

figure
plot(u1d)

inside of example, infinite figures appear.

Can someone please explain to me if it is possible to plot the points of u1d and compare them with the interpolated ones at u(1)?

I have tried to construct

u(1)=interp1(time,u1d,t,'linear');
u(2)=interp1(time,u2d,t,'linear');
u(3)=interp1(time,u3d,t,'linear');

outside of the ode45 function but error messages appear.

Thanks for reading.

Jaime.

Can you upload the data in a *.mat file, so we can run and test it ourselves?

[Jaime De La Mota Sanchis]

When you say data, do you mean u1d, u2d and u3d?

Edit: I will attach one example model and the example function

You have the vectors time, and u1d (etc) outside of the ode45 call. And you also have the output t from the ode45 call. So, why can't you run an interpolation and compare the two?

I have tried it your way and it works. Thanks.

I will move it to an Answer then.

You have the vectors time, and u1d (etc) outside of the ode45 call. And you also have the output t from the ode45 call. So,you can run an interpolation after calling ode45 (not inside).
