This is the core of the function apply on a serial matrix to compute when A is memorized in a sparse storage. In this case the routine converts it to a dense storage and then calls the array version of itself. That is the one implementing the different functions. It is the function to modify if ones want to interface a new function that was not previously available or a new algorithm (variant) for an already existing function.
