摘要
介绍了用CASIO fx—4850P计算器按间接法平差高程控制网,利用法方程中系数矩阵对称正定的特点,直接生成法方程式的系数矩阵。由于CASIO fx—4850P计算器程序容量28500字节,考虑到野外工作受环境制约及其工作的流动性,该计算器能够容纳一般的常用测量计算程序,携带和计算都非常方便。程序经过实例验算,精度很好,实用性强。
This paper introduces using Casio fx-4850P calculator to adjust height control network by indirect adjustment method.Using the characteristic which the matrix of coefficients of normal equation is symmetry and positive define,the matrix of coefficients of normal equation is created directly.The capacity of Casio fx-4850P calculator is just 28500 bytes.So thinking that the field work is amulatory and restricted by condition,this calculator can contain common survey calculating programs,and it is portable and calculating expediently.This program endures the practical calculating tests.The precision and practicability is very good.
