A sparse matrix is a matrix in which most of the elements are zero.

Another sparse matrix.

A sparse matrix is one which normally contains a large proportion of elements whose value is 0. There is no exact proportion at which a matrix becomes sparse.

write a programe to build a sparse matrix as an array. write function to check if the sparse matrix is a square, diagonal,lower triangular, upper triangular or tridiagonal matrix

A sparse matrix is matrix that allows special techniques to take advantage of large number of zero element.

Application of sparse matrix is classification and relationship analysis in large data base system - SPARCOM
