Write two separate MATLAB script m-files to implement this task: one that produces the result using MATLAB array processing operations as we learned about in Chapter 1; and one that builds up the array result element-byelement using an iteration programming construct. Add code to time your two implementations. Which is quicker and why?In this exercise you will write code to automatically identify a particular gait event: the foot strike of the left leg, which refers to the instant that the left heel touches the ground. The foot strike event can be determined by looking for troughs in the series of z coordinates of the ankle marker. The z coordinates represent the inferior–superior (i.e. foot–head) motion of the marker. Write a MATLAB script m-file that loads in the LAnkle_tracking.mat file and first produces a plot of the z-coordinates against time. The script should then search the list of z-coordinates and report any troughs. To begin with, consider a trough to be any value that is less than both the preceding and following valueWrite a MATLAB script m-file that loads in the LAnkle_tracking.mat file and first produces a plot of the z-coordinates against time.
