18.06 Linear Algebra

18.06 Linear Algebra (Spring 2010, MIT OCW). This consists of 34 video lectures given by Professor Gilbert Strang, on matrix theory and linear algebra. Emphasis is given to topics that will be useful in other disciplines, including systems of equations, vector spaces, determinants, eigenvalues, similarity, and positive definite matrices. (from
