Formats in which matrices are available.

delete_all_ssmc()

Remove all matrices from the SuiteSparseMatrixCollection.

delete_ssmc(name::AbstractString, group::AbstractString, format = "MM")

Remove the matrix with name name in group group and format format.

 fetch_ssmc(group::AbstractString, name::AbstractString; format="MM")

Download the matrix with name name in group group. Return the path where the matrix is stored.

 fetch_ssmc(matrices; format="MM")

Download matrices from the SuiteSparseMatrixCollection. The argument matrices should be a DataFrame or DataFrameRow. An array of strings is returned with the paths where the matrices are stored.

installed_ssmc()

Return a vector of tuples (group, name, format) of all installed matrices from the SuiteSparseMatrixCollection.

manage_ssmc(; sort_by::Symbol=:name, rev::Bool=false)

Opens a prompt allowing the user to selectively remove matrices from the SuiteSparseMatrixCollection.

By default, the matrices are sorted by name. Alternatively, you can sort them by file size on disk by specifying sort_by=:size. Use rev=true to reverse the sort order.

ssmc_db(; verbose::Bool=false)

Load the database of the SuiteSparseMatrixCollection. A summary of the statistics available for each matrix can be found at https://www.cise.ufl.edu/research/sparse/matrices/stats.html.

ssmc_matrices(ssmc, group, name)

Return a DataFrame of matrices whose group contains the string group and whose name contains the string name.

ssmc_matrices(ssmc, name)
ssmc_matrices(ssmc, "", name)

Return a DataFrame of matrices whose name contains the string name.

ssmc_matrices(ssmc, group, "")

Return a DataFrame of matrices whose group contains the string group.

Example: ssmc_matrices(ssmc, "HB", "bcsstk").
