From The Free On-line Dictionary of Computing (30 December 2018) :

     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.
