Sparse matrices
A sparse matrix is a matrix in which most of the elements are zero. By contrast, if most of the elements are nonzero, then the matrix is considered dense. The number of zero-valued elements divided by the total number of elements—for example,
Sparse matrices are incredibly useful in scientific computing, where they can provide significant computational and storage efficiencies. Many large-scale systems give rise to mathematical models that operate with sparse ...
