%% Second Derivative of Vector % Calculate the acceleration of an object from a vector of position data. %% % Create a vector of position data. % Copyright 2015 The MathWorks, Inc. p = [1 3 6 10 16 18 29]; %% % To find the acceleration of the object, use |del2| to calculate the % second numerical derivative of |p|. Use the default % spacing |h = 1| between data points. L = 4*del2(p) %% % Each value of |L| is an approximation of the instantaneous acceleration % at that point.
