Jerk is the rate of change in acceleration over time of an object. So, if given the position of an object over time in the form of a 1-by-N vector, return the indices i where there is nonzero jerk.
Super rad bonus hint: The signal you need to find the jerk of will be given by the variable sig, created with the commands
h = 0.065; % stepsize t = -10:h:10; sigCoefs = 2*rand(1,3)-1; sig = polyval(sigCoefs,t); breakPoint = randi(length(sig)-2)+1; sig(breakPoint) = (1.01)*sig(breakPoint); % this creates a nonzero jerk
Check the signal visually with
Now, using just sig, determine breakPoint.
