Sparse matrix compression and reduction.A matrix with nonzero element is less, and zero element is relatively more, so the matrix called sparse matrix, the sparse matrix storage we don t have to entirely in a two-dimensional array to store, you can use a triad, or any one of only three columns of sparse matrix can use a two-dimensional array to store,Asked to put the given sparse matrix by for ternary group said At the same time convert triples to sparse matrix form.
