The joint bidiagonalization method for large GSVD computations in finite precision
Zhongxiao Jia, Haibo Li
The joint bidiagonalization (JBD) method has been used to compute some extreme generalized singular values and vectors of a large regular matrix pair , where we propose th…
The convergence of the Generalized Lanczos Trust-Region Method for the Trust-Region Subproblem
Zhongxiao Jia, Fa Wang
Solving the trust-region subproblem (TRS) plays a key role in numerical optimization and many other applications. The generalized Lanczos trust-region (GLTR) method is a well-known…
On choices of formulations of computing the generalized singular value decomposition of a large matrix pair
Jinzhi Huang, Zhongxiao Jia
For the computation of the generalized singular value decomposition (GSVD) of a large matrix pair of full column rank, the GSVD is commonly formulated as two mathematically…
Regularization Properties of the Krylov Iterative Solvers CGME and LSMR For Linear Discrete Ill-Posed Problems with an Application to Truncated Randomized SVDs
Zhongxiao Jia
For the large-scale linear discrete ill-posed problem or with contaminated by Gaussian white noise, there are four commonly used Krylov solvers: LSQR and…
