A note on the growth factor in Gaussian elimination for generalized Higham matrices

, 2013
The Higham matrix is a complex symmetric matrix A=B+iC, where both B and C are real, symmetric and positive definite and $\mathrm{i}=\sqrt{-1}$ is the imaginary unit. For any Higham matrix A, Ikramov et al.

An inverse LU preconditioner based on the Sherman–Morrison formula

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
An approximate inverse LU preconditioner is constructed based on the Sherman–Morrison formula. Applying recursively that inversion formula a multiplicative decomposition of the inverse of a matrix is obtained.
