| 摘 要： | 随着计算机件技术与数学科学的不断发展 ,虽然测量平差技术已经取得了很大的进步 ,但在技术实现方面还存在不少问题。目前 ,市场上推出的测量平差软件或平差大全 ,大都是在PC— 15 0 0机上用QBASIC或FORTRAN语言进行平差处理 ,在使用时常会遇到无法满足现实测绘工作的要求 ,而且很难对其源程序进行改进。本文充分利用矩阵行列式初等变换性质、C语言中指针动态性优于函数递归调用的特性来实现并优化了测量平差电算程序中的关键技术———矩阵求逆

| Abstract: | Along with the development of computer technology and mathematics,although the progress of survey adjustment technology was greatly made,it had a lot of question lied in.At present,a lot of survey adjustment soft wares in the market supplied are mainly programmed on the PC-1500 through QBASIC or FORTRAN language,which does not meet the need of the survey in reality,and it is difficult to optimize the original program.the paper made good use of computer technology and matrix theory knowledge realizing and optimizing the crux-matrix inversion of the survey adjustment. |
