Subject: want to save internal data from ode45 - is this true?

I want to save internal data from ode45, but NOT from the intermediate 
timesteps (only the full timestep).

I found this:
http://www.mathworks.co.uk/matlabcentral/newsreader/view_thread/246590

And tried to implement it - but I think it's wrong.

If the last line(s) of the mass-matrix is zero, the ode45-solver will 
not even solve it.

Am I right? Isn't there any way of only solving the whole (full) 
timestep internal values of ode45?
