substitute for ode23s

[humanengr]

Matlab code I've inherited uses ode23s with either T= [T0 TFINAL] or T= [T0 T1 ... TFINAL] in

> [r.T r.Y] =
> ode23s(@(t,y)OdeFn(t,y,d),T,y0,opts);

I see that ode2r works well as a substitute for T= [T0 TFINAL], but for T= [T0 T1 ... TFINAL] it yields

> error: invalid conversion from real matrix to real
> scalar

and a number of errors of the form:

 

> error: octave_base_value::array_value(): wrong type
> argument `<unknown type>'

Is there something I can do in Octave that is equivalent to ode23s for the T= [T0 T1 ... TFINAL] case?

Thanks,
