DGMRES: A GMRES-type algorithm for Drazin-inverse solution of singular nonsymmetric linear systems. (English) Zbl 0982.65043
The paper deals with the linear system $Ax= b,\tag{1}$ where $$A\in \mathbb{C}^{N\times N}$$ is a singular matrix and $$\text{ind}(A)$$ is arbitrary. The author uses a generalized minimal residual (GMRES)-type algorithm in order to obtain the Drazin-inverse solution of (1).
