How to calculate Relative Positive Acceleration (RPA)

Hi, Could anybody help me for MATLAB coding. Let second by second vehicle speed data samples is V (km/h) = 0 3 7 8 14 20 24 22 21 15 11 9 5 2 0 4 6 17 13 6 3 0. How to calculate Relative Positive Acceleration (RPA) using this formula:

With being the acceleration at time step i, (only ai > 0 (m/s2), vi being the vehicle speed at time step i (m/s) and being the total trip distance (m).

The vehicle acceleration was calculated from consecutive vehicle speed samples according to the following equation.
