enum LA::Enums::LSMethod

Overview

Enumeration of methods for solving least squares problems.

• Auto: Automatically choose the best method (currently QR).
• QR: Use QR factorization (fast, good for well-conditioned problems).
• Orthogonal: Use orthogonal factorization with pivoting (good for rank-deficient problems).
• SVD: Use singular value decomposition (most robust, handles rank deficiency well).
• LS: Alias for QR.
• LSY: Alias for Orthogonal.
• LSD: Alias for SVD.
