sparse

   A sparse {matrix} (or {vector}, or {array}) is one in which
   most of the elements are zero.  If storage space is more
   important than access speed, it may be preferable to store a
   sparse matrix as a list of (index, value) pairs or use some
   kind of {hash} scheme or {associative memory}.
