【Abstract】 Preconditioned Method is widely applied in large parallel computation.Local orthogonalization is a good choice to improve the condition number of matrix.This paper discussed how to solve a sparse system of linear equations by local orthogonalization,and compared the computing speed of different methods.Indicated from the example,this preconditioned method is very efficient to these similar problems.更多还原
