A very specific request!
Here's a write-up based on the book:
The basic idea of the QR algorithm is to decompose the matrix A into the product of an orthogonal matrix Q and an upper triangular matrix R, and then to multiply the factors in reverse order to obtain a new matrix A' = RQ. The process is repeated until convergence.
Av = λv
The symmetric eigenvalue problem is a fundamental problem in linear algebra and numerical analysis. The book you're referring to is likely "The Symmetric Eigenvalue Problem" by Beresford N. Parlett.
The symmetric eigenvalue problem is a classic problem in linear algebra, which involves finding the eigenvalues and eigenvectors of a symmetric matrix. The problem is symmetric in the sense that the matrix is equal to its transpose. This problem has numerous applications in various fields, including physics, engineering, computer science, and statistics. parlett the symmetric eigenvalue problem pdf
