摘要：

A new preconditioned conjugate gradient method for solution of large real sparse symmetric linear equations in 3D-electromagnetic field analysis is presented. Three relaxation factors are used to reduce the computation time of each iterative step of the conjugate. gradient method and improve rate of convergence. Numerical examples show that the method is problem-independent in a certain extent, and could decrease the computation time over 50% than the conventional method.
