A distributed-memory parallel implementation of the sparsified QR factorization algorithm using the TaskTorrent runtime system. This repository provides efficient QR factorization for large sparse ...
Abstract: Two nonlinear zeroing neural network (ZNN) models with prescribed-time convergence for time-dependent matrix LR and QR factorization are proposed in this ...
We present optimal parallel QR factorization algorithms with reduced communication overhead. QR factorization is widely applied to solve various problems in numerical linear algebra. Our focus is on ...
Least-squares reverse time migration (LSRTM) has become a popular research topic and has been practically applied in recent years. LSRTM can generate preferable images with high signal-to-noise ratio ...
We present an algorithm to generate complete evolutionary profiles that represent the topology of the molecular phylogenetic tree of the homologous group. The method, based on the multidimensional QR ...
My linear algebra textbook (Advanced Linear Algebra,Steven Roman, pg. 217) says for QR factorization: any real or complex matrix is amenable to a decomposition A = QR, with Q orthonormal columns and R ...
