//! Linear algebra utilities: matrix decompositions and correlation
//! handling.
//!
//! [`decomp`] holds the general-purpose factorizations (Cholesky, QR,
//! SVD, symmetric eigen). On top of them sit the correlation tools:
//! empirical correlation matrices (estimated pairwise, stressed by hand,
//! or copied from a term sheet) frequently fail positive
//! semi-definiteness; [`nearest_correlation`](nearest_correlation::nearest_correlation)
//! repairs them with the alternating-projections algorithm of Higham
//! (2002), and [`cholesky`](cholesky::cholesky) factorizes the result for
//! correlated simulation.
