If not, then MATLAB does NOT know the matrix is sparse, and does not use a sparse factorization. How sparse is A? Many people think that a matrix that is half full of zeros is "sparse". That would be a waste of time. On a matrix that size, you need something that is well over 99% zeros to truly gain from a sparse factorization of the matrix. .
