An RRQR factorization or rank-revealing QR factorization is a matrix decomposition algorithm based on the QR factorization which can be used to determine the rank of a matrix. [1] The singular value decomposition can be used to generate an RRQR, but it is not an efficient method to do so. [2] An RRQR implementation is available in MATLAB. [3]
Data placement of Rectangular Micro QR Code. Rectangular Micro QR Code places data in the same way as QR code in two-module wide columns [2]: 7.7.3 commencing at the lower right corner of the symbol and running alternately upwards and downwards from the right to the left.
Instead, the QR algorithm works with a complete basis of vectors, using QR decomposition to renormalize (and orthogonalize). For a symmetric matrix A , upon convergence, AQ = QΛ , where Λ is the diagonal matrix of eigenvalues to which A converged, and where Q is a composite of all the orthogonal similarity transforms required to get there.
LAPACK ("Linear Algebra Package") is a standard software library for numerical linear algebra.It provides routines for solving systems of linear equations and linear least squares, eigenvalue problems, and singular value decomposition.
QR decomposition, a decomposition of a matrix QR algorithm, an eigenvalue algorithm to perform QR decomposition; Quadratic reciprocity, a theorem from modular arithmetic; Quasireversibility, a property of some queues; Reaction quotient (Q r), a function of the activities or concentrations of the chemical species involved in a chemical reaction
