    • Error bound of the multilevel adaptive cross approximation (MLACA) 

      Chen, Xinlei; Gu, Changqing; Heldring, Alexander; Li, Zhuo; Cao, Qunsheng (2016-01)
      Article
      Open Access
      An error bound of the multilevel adaptive cross approximation (MLACA 1, which is a multilevel version of the adaptive cross approximation-singular value decomposition (ACA-SVD), is rigorously derived. For compressing an ...
    • Nested fast adaptive cross approximation algorithm for solving electromagnetic scattering problems 

      Fang, Xiaoxing; Heldring, Alexander; Rius Casals, Juan Manuel; Chen, Xinlei; Cao, Qunsheng (IEEE Microwave Theory and Techniques Society, 2020-09-28)
      Article
      Open Access
      In this paper, a Nested Fast Adaptive Cross Approximation (NFACA) algorithm is presented to accelerate the solution of electromagnetic scattering problems. It is based on the Fast Adaptive Cross Approximation (FACA) and ...
