Description: MIT A 2020 Vision of Linear Algebra, Spring 2020 Instructor: Gilbert Strang View the complete course: ocw.mit.edu/2020-vision YouTube Playlist: youtube.com/playlist?list=PLUl4u3cNGP61iQEFiWLE21EJCxwmWvvek This new video computes the nullspace of any matrix A. The equation Ax = 0 is reduced to row echelon form Rx = 0. Then all solution vectors are combinations of "special solutions.” We understand the pieces of R from the factorization A = CR.
