Using an electromagnetic tracking device, the position of the gastroscope relative to the(More)
—In this paper, three preconditioned parallel mul-tisplitting methods are established for solving the large sparse linear systems, including local preconditioned parallel mul-tisplitting relaxation method, global preconditioned parallel multisplitting relaxation method and global preconditioned nonstationary parallel multisplitting relaxation method.
