RemarksMany applications give rise to very large matrices which consist mostly of zero elements.
When working with sparse matrices, it is important to keep in mind that many operations do not respect sparsity. For example, the product of two sparse matrices is not necessarily sparse, nor is the inverse of a sparse matrix.
