matlab， computing matrix by QR

详 情 说 明

One way to compute matrices in MATLAB is by using the QR decomposition. The QR decomposition is a matrix factorization method that expresses a matrix as the product of an orthogonal matrix and an upper triangular matrix. This method is useful for solving a wide range of problems in linear algebra, including linear least squares, eigenvalue problems, and singular value decomposition. It is also commonly used in applications such as signal processing, control theory, and numerical optimization. By implementing the QR decomposition in MATLAB, users can efficiently and accurately manipulate matrices for a variety of computational tasks.
