For an (m \times n) matrix (A):

Strang’s gem: “The inverse of (A) is like the reciprocal, but much harder to compute. Never compute it unless you have to.”

(C(A^T)): all (A^T y). Dimension = (r). Actually the same as column space of (A^T). Open the LaTeX or handwritten notes from GitHub

The official repository for the course (often numbered 18.06) is MIT OpenCourseWare. This is the primary source for high-quality PDF materials. When you download the course materials from OCW, you aren't just getting a syllabus; you typically gain access to:

These notes follow Strang’s “big picture” approach: start with elimination, meet the four subspaces, then diagonalization, and end with singular values. Strang’s gem: “The inverse of (A) is like

Orthogonal vectors, projections, Gram-Schmidt process, determinants, eigenvalues, eigenvectors, and diagonalization.
