% 10/21/2009 1:40 PM % Function Name: digits % Inputs: 1. double - an integer % Outputs: 1. double array - a vector of digits % % Function Description: % Write a function that takes in an integer and returns a vector % containing all of the digits in the order they appear in the input. % Your function should work for all integers. Simply ignore the negative % sign if negative. % % You must use recursion to receive credit. You may find it helpful to % start conceptually with the recursive call and to work your way % backwards to the terminating condition. Remember to use a wrapper % function to handle undesirable inputs to your recursive function if % necessary. Do NOT use any other built-in functions besides length,
