Iterative Solution of Regularization to Ill-conditioned Problems in Geodesy and Geophysics被引量：5
《Journal of Geodesy and Geoinformation Science》2019年第1期59-65,共7页Yongwei GU Qingming GUI Xuan ZHANG Songhui HAN 
The National Natural Science Foundation of China(41174005,41474009).
In geodesy and geophysics,many large-scale over-determined linear equations need to be solved which are often ill-conditioned.When the conjugate gradient method is used,their ill-conditioning effects to the solutions ...
