## Public overview

QR decomposition is a recurring research-paper notation family. Factors a matrix into an orthogonal-column factor and an upper-triangular factor for stable linear solves and least squares.

QR decomposition: Factors a matrix into an orthogonal-column factor and an upper-triangular factor for stable linear solves and least squares. Example: Separate the matrix into orthogonal directions and triangular coordinates.
