This problem is created to test an alternative Cody scoring system. It is based on the current one, but few changes are introduced. The main difference is that strings generate nearly same size as other arrays so '12345'-'0' won't be smaller than [1 2 3 4 5]. There is also improvement of scoring when ans is used.Your goal is to write a function that for given n creates spiral matrix like in problem <a href = "http://www.mathworks.com/matlabcentral/cody/problems/944">944</a>. You can choose one or more ways to do this:<ul><li>Clean Code - without any kind of cheating,</li><li>Small Size - using cheats based on scoring system like regexp or 'chars'-'0',</li><li>Hack+100 - if you really want, I can't stop you from hacking this problem, set size to 100 in this case, please.</li></ul>Enjoy!This problem is related to problems <a href = "http://www.mathworks.com/matlabcentral/cody/problems/944">944</a>, <a href = "http://www.mathworks.com/matlabcentral/cody/problems/2033">2033</a>, <a href = "http://www.mathworks.co.uk/matlabcentral/cody/problems/2390">2390</a>, ... and others which I don't remember now :-)
