The Left NullspaceStrang shows how these four spaces provide a complete "map" of any matrix. 4. Orthogonality and Least Squares
From these, you get:
is an orthogonal matrix (its columns are perpendicular and have length 1), making it numerically stable and great for least squares. lecture notes for linear algebra gilbert strang
