Details:

The following code


A=eye(2);,f=@(t,y) A*y;,ode15s(f,[0,1],[1,1])


does not work, while it works in Matlab and works in Octave with ode23 and
ode45 instead of ode15s. I guess it is enough to change y0 to y0(:) around
lines 56 and 59 of check_default_input.m (probably the same with yp0).
