| Abstract: | The idea of symbolic iterative method is introduced briefly. Taking common inverse problems in ellipsoidal geodesy for example,they are solved using symbolic iterative method by means of computer algebra system Mathematica with powerful function for symbolic operation,and symbolic expressions of their analytic solutions are available. The results show that processes of symbolic iteration method are concise,and this method can be used to solve other similar mathematical problems in geodesy. |
