Lecture Notes For Linear Algebra Gilbert Strang Jun 2026

Given a matrix (A) with independent columns, the projection of (b) onto (C(A)) is: [ p = A(A^TA)^-1A^T b ] The projection matrix: (P = A(A^TA)^-1A^T). Properties: (P^T = P) and (P^2 = P).

Strang simplifies the often-confusing world of . He explains them as the "steady states" or "natural frequencies" of a system, leading into the Singular Value Decomposition (SVD) —the crown jewel of linear algebra.

The essay cannot conclude without addressing the climax of the course: the Spectral Theorem. When Strang arrives at eigenvalues and eigenvectors, the text achieves a symphonic resolution. He explains them as the "steady states" or
