1//! Linear solvers for BEM
2//!
3//! This module provides various solvers for BEM systems, re-exporting
4//! functionality from `math-solvers`.
5//!
6//! - [`direct`] - Direct LU factorization
7//! - [`cgs`] - Conjugate Gradient Squared
8//! - [`bicgstab`] - BiCGSTAB
9//! - [`gmres`] - GMRES (recommended for large BEM problems)
10//! - [`fmm_interface`] - Interface to use FMM operators with iterative solvers
11//! - [`preconditioner`] - Preconditioners (ILU, AMG, etc.)
12//! - [`batched_blas`] - Batched BLAS operations (native only)
