Matrix decompositions | Numerical linear algebra
In linear algebra, a QR decomposition, also known as a QR factorization or QU factorization, is a decomposition of a matrix A into a product A = QR of an orthogonal matrix Q and an upper triangular matrix R. QR decomposition is often used to solve the linear least squares problem and is the basis for a particular eigenvalue algorithm, the QR algorithm. (Wikipedia).

QR-Decomposition for a 2x2 Matrix
EDIT: At 3:00, it should be (Q_2 inverse)Q_1 = R_2(R_1 inverse) Linear Algebra: We give a general formula for a QR-decomposition of a real 2x2 matrix; that is, we show how to decompose any 2x2 matrix A as a product QR where Q is orthogonal and R is upper triangular. We also note one se

Gram Schmidt process for QR decomposition using Python
#LinearAlgebta #DataScience In this video tutorial I use Python to explain the easy steps of the Gram Schmidt process. Following the steps of this process yields a set of orthonormal basis vectors for the (sub) space spanned by the column vectors of a matrix. Each new column vector is orth
