Improved Seed Methods for Symmetric Positive Definite Linear Equations with Multiple Right-hand Sides
Abdou M. Abdel-Rehim, Ronald B. Morgan, Walter Wilcox
We consider symmetric positive definite systems of linear equations with multiple right-hand sides. The seed conjugate gradient method solves one right-hand side with the conjugate…

Deflated and restarted symmetric Lanczos methods for eigenvalues and linear equations with multiple right-hand sides
Abdou M. Abdel-Rehim, Ronald B. Morgan, Dywayne A. Nicely +1
A deflated restarted Lanczos algorithm is given for both solving symmetric linear equations and computing eigenvalues and eigenvectors. The restarting limits the storage so that fi…
