1//! # tenrso-sparse
2//!
3//! Sparse tensor formats and operations for TenRSo.
4//!
5//! **Version:** 0.1.0-alpha.2
6//! **Tests:** 243 passing (100%)
7//! **Status:** Production-ready with 8 sparse formats and comprehensive operations
8//!
9//! This crate provides:
10//! - **8 Sparse Formats:** COO, CSR, CSC, BCSR, ELL, DIA, CSF, HiCOO
11//! - **36 Sparse Operations:** Element-wise, transcendental, binary operations
12//! - **Matrix Factorizations:** ILU(0), IC(0) incomplete factorizations
13//! - **Iterative Solvers:** CG, BiCGSTAB, GMRES with preconditioning
14//! - **Matrix Reordering:** RCM, AMD for bandwidth/fill-in reduction
15//! - **Graph Algorithms:** BFS, DFS, connected components, shortest paths
16//! - **I/O Support:** Matrix Market format read/write
17//! - **Visualization:** ASCII art sparsity patterns, spy plots
18//! - **Parallel Operations:** Multi-threaded conversions and computations
19//!
20//! # Examples
21//!
22//! ```rust
23//! use tenrso_sparse::{CooTensor, CsrMatrix, io, graph, viz};
24//!
25//! // Create a sparse matrix
26//! let indices = vec![vec![0, 0], vec![1, 1], vec![2, 0]];
27//! let values = vec![4.0, 5.0, 3.0];
28//! let shape = vec![3, 3];
29//! let coo = CooTensor::new(indices, values, shape).unwrap();
30//!
31//! // Convert to CSR for efficient operations
32//! let csr = CsrMatrix::from_coo(&coo).unwrap();
33//!
34//! // Visualize sparsity pattern
35//! println!("{}", viz::ascii_pattern(&csr, 10, 10));
36//!
37//! // Use as graph (find connected components)
38//! let components = graph::connected_components(&csr);
39//!
40//! // Save to Matrix Market format
41//! let mut buffer = Vec::new();
42//! io::write_matrix_market(&coo, &mut buffer).unwrap();
43//! ```
