Sparse matrices are a special case of 2D matrices, where only non-zero elements are stored and displayed for efficiency. A sparse matrix typically has a high percentage of zero elements. Strings. Strings are arrays of characters. Variables and Assignments. OML language scripts manipulate data through variables.

Lukarski, Apr 11, 2013, Uppsala What is a Sparse Matrix?

2018-08-09 2020-02-04 2021-03-25 Sparse-matrix dense-matrix multiplication (SpMM) is a fundamental linear algebra operation and a building block for more complex algorithms such as finding the solutions of linear systems, computing eigenvalues through the preconditioned conjugate gradient, and multiple right-hand sides Krylov subspace iterative solvers.

A more practical definition is that a matrix is sparse if the A sparse matrix is a matrix in which most elements are zeroes. This is in contrast to a dense matrix, the differentiating characteristic of which you can likely figure A sparse matrix data structure avoids storing some or all zero entries. The result is a more compact structure that uses less memory. In some cases, without a Sparse Matrices¶.

For a sparse matrix, S, the nnz function returns the number of nonzero elements in the matrix, and the nzmax function returns the amount of storage allocated for nonzero matrix elements. If nnz(S) and nzmax(S) return different results, then more storage might be allocated than is actually required. Leveraging sparse matrix representations for your data when appropriate can spare you memory storage.
