Why doesn't it work ?

That's better, thanks, but why not edit the original Q? and put the code there? Will it not let you edit your own Q?.
But, you've not taken the advice to heed -- the problem is still that you're not using the "dot" operators...

As the error suggests, use element wise powee .^
