The QR-decomposition of a matrix is used to solve nearly singular, overde-termined, and underdetermined systems of linear equations. In specialized form, it is an important component of the QR-algorithm, which computes all eigenvalues and eigenvectors of a matrix. The multicomputer program for QR-decomposition is an application of recursive doubling, but several interesting complications arise.
