Modify the function myStats (from question-1) and write myStats_2 so that the input argument k is optional. In case this argument is omitted, then the function myStats_2 returns the smallest and the largest element in the myArray. Write a script helpMyStats_.m which reads all the elements of myArray and the value k from the user and displays the result by calling myStats_2 function with the appropriate input data. Also test various ways to call myStats_2.
