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 ...
Multifrontal QR algorithm, which consists of symbolic analysis and numerical factorization, is a high-performance algorithm for orthogonal factorizing sparse matrix. In this work, a graph ...
Abstract: Motivated by a superfluous zero extraction problem arising in the discrete-time J-spectral factorization of polynomial matrices, we propose an algorithmic solution to hyperbolic QR ...
