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. parlett the symmetric eigenvalue problem pdf
