 ====== Math 445 HW2: Bubble sort ======
-**Problem 1.** Write a Matlab function ''mysort'' that takes an input vector ''x'', rearranges its components so they are in increasing order, and then returns the sorted vector. For example, ''mysort([0.38 0.57 0.22])'' should return ''[0.22 0.48 0.57]''. Your ''mysort'' function should use the "bubble sort" algorithm and just basic comparisons and control-flow operations. That is, no cheating by using Matlab's ''sort'' function!

 **Problem 2.** Test ''mysort'' on a random vector of length 4. That is, set ''x = rand(4,1)'' and then ''y = mysort(x)''. Verify by eye that ''x'' and ''y'' have the same set of elements and that ''y'' is sorted correctly. If there are any problems, go back and fix your ''mysort'' function.
