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…
Deflated Iterative Methods for Linear Equations with Multiple Right-Hand Sides
Ronald B. Morgan, Walter Wilcox
A new approach is discussed for solving large nonsymmetric systems of linear equations with multiple right-hand sides. The first system is solved with a deflated GMRES method that…
Deflated GMRES for Systems with Multiple Shifts and Multiple Right-Hand Sides
Dean Darnell, Ronald B. Morgan, Walter Wilcox
We consider solution of multiply shifted systems of nonsymmetric linear equations, possibly also with multiple right-hand sides. First, for a single right-hand side, the matrix is…
