    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


    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).
