This is the fourth post in an article series about MIT's course "Linear Algebra". In this post I will review lecture four on factorizing a matrix A into a product of a lower-triangular matrix L and an upper-triangular matrix U, or in other words A=LU. The lecture also shows how to find the inverse of matrix product A·B, how to find the inverse of transposed matrix AT, and introduces permutation matrices.
