I have a vector, R=[17 0 -10] which represents a coordinate of a mass. I modeled the equations of motions in Simulink and R vector changes as time goes by correctly. However, I want to find the ratio between the current value of R and previous value of R. For example,
at time=0, R(i)=[17 0 -10]
at time=0+dt, R(i+1)=[17.1 0 -9.99]
So, I want to find R(i+1)/R(i).
