Comment(by ericfode):

 An in-place dot product is not possible with out allocating enough memory
 to copy the original item (a) into a temporary data structure, defeating
 the purpose of a in-place copy. Consequently, this does not work.

 Check out Wikipedia for an explanation of how to do a dot product.

 Use
 a = dot(a,identity(3))
