Anyone have much knowledge on the ODE solvers in matlab? I have an ODE and I want to specificy whether the input is time or the y value for the dy/dt problem.

Could you please be more specific.
You can only have one variable in an ODE and in this case that variable is t, i.e. the equation is

dy/dt=f(t)

where f is some function of t (and ONLY of t, otherwise it is a PDE).
In order to have a single solution to this ODE you then only need the initial value of y at time 0, i.e. y(0).

Cool thanks I think thats what I was looking for.
