2. Write a MATLAB function that sorts the input array of real numbers num_arr in the ascending order and outputs i the result and i) the number of swaps required. The sort must implement the Bubble Sort algorithm, which is as follows: i. Repeatedly step through the array ii. Check the adjacent elements of the array ii. If they are in the wrong order - swap them. Check the wikipedia site for more information: http://en.wikipedia.org/wiki/Bubble_sort a. Test your function on the array given on wikipedia: [6 5 318724] b. How many swaps do you get
