[t,y] = odeXX(odefun,tspan,y0)
Say I have a solver odeXX, and the `tspan = [0 0.005]`. It seems that for any ode solver in MATLAB, they integrate by breaking `tspan` into multiple steps (some adaptive like ode45 and some non-adaptive). But I am looking for the most primitive one--just integrate from `0` to `0.005` in one step. Which ode solvers allow me to do this and how to specify this?

None - all are adaptive.
But it should be no problem to program such a primitive solver on your own.
Best wishes

How many variables are involved? Is your odefun dependent on only t, only y, or both t and y? What is the length of your y0?
