I saw both ode45(@springmass,....) and ode45('springmass',....), what are the difference?

Both 'springmass' and @springmass refer to the function springmass. Both should work. They don't have difference here.

Are the percentages in the definition of rise time, overshoot measured from the final value, or the size of the input change?

They are measured from the size of the input change. That is, for a system whose target has changed from 10 to 20, the rise time is the time to go from 10.5 to 19.5. If it overshoots to 21, that's 10% overshoot.
