Further applications of a splitting algorithm to decomposition in variational inequalities and convex programming A classical method for solving the variational inequality problem is the projection algorithm. We show that existing convergence results for this algorithm... Tseng, P - 《Mathematical ...
An accurate and stable algorithm, Orthogonal-Triangular Decomposition Algorithm (OTDA) is for the first time presented in the field of chemistry. The basic principle of OT Multivariate Calibration Algorithm (OTMCA) is investigated. Complexes of sodium tripo-lyphosphate (STTP), sodium sulfate (SS) ...

D. Sweet's clever QR decomposition algorithm for Toeplitz matrices is considered. It requires only O( n 2) flops to factor an n × n matrix. We analyze the algorithm to point out its deficiencies, and compare it against two other Toeplitz solvers....

A class of sufficient conditions is given to ensure that the sum a + b in a ring R, is equivalent to a sum x + y, which is an orthogonal Pierce decomposition. This is then used to show that a lower triangular matrix, with a regular diagonal is equivalent to its diagonal iff the ...
Summary: We propose an implicit method for applying orthogonal transformations on both sides of a product of upper triangular $2\times 2$ matrices that preserve upper triangularity of the factors. Such problems arise in Jacobi type methods for computing the singular value decomposition of a product...
This decomposition is applied to the elastic energy. Based on the properties of the higher order energy, two values of the wave number are selected. Depending on the desired precision one of those values can be used as optimum cutoff wave number to properly capture a wave field....
