A Julia package for graph and network algorithms using matrix-based representations.
MatrixNetworks.jl is a Julia package that provides a collection of network algorithms using a matrix-based approach. It treats graphs as adjacency matrices, blurring the distinction between linear algebra and network analysis to offer a flexible and intuitive interface for computational tasks. This enables seamless integration of graph operations with linear algebra functions.
Julia developers and researchers working on network analysis, graph algorithms, or computational tasks that benefit from a unified matrix-network representation. It is particularly suited for those familiar with linear algebra who prefer matrix operations over traditional graph data structures.
Developers choose MatrixNetworks.jl over alternatives like LightGraphs.jl or Graphs.jl because it eliminates the distinction between matrices and networks, allowing graphs to be represented and manipulated as adjacency matrices. This provides a more intuitive interface for users comfortable with linear algebra and simplifies the implementation of graph algorithms through matrix operations.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Graphs are treated as adjacency matrices (SparseMatrixCSC or MatrixNetwork), enabling seamless integration with linear algebra operations, as shown in functions like bfs(A, u) where A is a matrix.
Includes BFS, strongly connected components, bipartite matching, and clustering coefficients, with enriched outputs such as reduction matrices from scomponents via enrich(sc).
Provides accessible datasets via matrix_network_datasets() and load_matrix_network, facilitating quick experimentation, as demonstrated in examples like load_matrix_network("clique-10").
Blurs the distinction between matrices and networks, making it intuitive for those familiar with matrix operations, as emphasized in the package's philosophy.
Compared to established packages like Graphs.jl, MatrixNetworks.jl has a smaller community and fewer third-party extensions, potentially lacking tools for visualization or advanced graph manipulations.
Documentation is primarily available through Julia's REPL (e.g., ?bfs), which may be less convenient than web-based documentation or comprehensive tutorials for new users.
While matrix operations are powerful, they might introduce overhead for certain graph algorithms on very large or sparse graphs, where traditional graph structures could be more memory or computationally efficient.
