Hi all -
I am trying to solve a differential equation with ode45 that has two
input variables and one output, but one of the input variables is
dependent on the other. When I try searching for anything like this it
is to no avail (maybe I don't know what to search for).
Anyway, the equation is
u_dot = 0.5*e_dot+1.64*(e-1.14*Vf_dot)
where e = Vf-Vl, Vl is my input, and Vf is my output. The value of u is
then fed into another system (which I do have the diff. eq. for) to get
Vf, if that helps.
Could someone give me some pointers on how to do this? Thanks.
-Ron
