Rank Revealing QR Methods for Sparse Block Low Rank Solvers
Solving linear equations of type Ax=b for large sparse systems frequently emerges in science and engineering applications, which creates the main bottleneck. In spite that the direct methods are costly in time and memory consumption, they are still the most robust way to solve these systems. Nowadays, increasing the amount …
