Harvard Applied Math 205 is a graduate-level course on scientific computing and numerical methods. This video introduces the QR decomposition, whereby a rectangular matrix can be written as the product of an orthogonal matrix and upper triangular matrix. The video shows why the QR decomposition is useful for solving linear least-squares problem.
