Using ode45 variables in non-differential equations

I'm looking to take the variables that I am using in my differential equations and apply a conversion to get the value for other variables that are functions of these variables.

That was very poorly worded so here is just an example of my code:

function dy = odeequation(t,y) dy = zeros(6,1);

z = y*(1-0.876*exp(-0.014*t));

dy(1) = some function;

...

dy(6) = some other function;

Before I did not have the dz term because this is my conversion. I want to plot z against time. How can I do that?

Thanks!

Calculate z from the results you obtained for y after your call to the ODE-integrator:

[T,Y]=ode45(...);
for k=1:6
  Z(:,k)=Y(:,k).*(1-0.876*exp(-0.014*T));
end

Best wishes
