It has been observed in numerical computations that convergence of ICCG for the A-V method is faster than that for the A method. This phenomenon is found to be explained by the fact that, in the A-V method, the preconditioning eliminates the small singular values which deteriorate the condition number while they remain after the preconditioning in the case of the A method.IEEEJournal Articleapplication/pdfhttp://hdl.handle.net/2115/38718https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/38718/1/igarashi02.pdf0018-9464AA00667933IEEE Transactions on Magnetics3825655682002-03enginfo:doi/10.1109/20.996148© 2002 IEEE.
