yeah he should not ,for the commun interest and knowledg

I dont agree with you ,because I don't see the bad thing of declaring **a as global variable ,
then I want you to edit my code using **a as parameter as you said "That's a bad solution. Simply pass it as a parameter. "so I can understand what you meant

waitting for you answer

If you try to use your functions (with the global variable) to operate several matrix, you'll see why it's a bad solution.
