Matrix Data from SuiteSparse Matrix Collection

Description

This dataset represents the collection of matrices from the SuiteSparse Matrix Collection. The structure of the dataframe mirrors the structure presented on the SuiteSparse Matrix Collection website.

Usage

SuiteSparseData

Format

A data frame with 2893 rows and 8 columns:

ID

Integer. Unique identifier for each matrix.

Name

Character. Name of the matrix.

Group

Character. Group name the matrix belongs to.

Rows

Integer. Number of rows in the matrix.

Cols

Integer. Number of columns in the matrix.

Nonzeros

Integer. Number of non-zero elements in the matrix.

Details

The SuiteSparse Matrix Collection is a large set of sparse matrices that arise in real applications. It is widely used by the numerical linear algebra community for the development and performance evaluation of sparse matrix algorithms. The Collection covers a wide spectrum of domains, including both geometric and non-geometric domains.
