摘　　要：导线网观测数据平差是一项繁重的工作,其平差过程涉及矩阵计算,由于算法复杂,较难利用传统编程语言进行程序实现和绘制误差椭圆。本文在MATLAB平台下,利用其强大的计算和可视化分析功能,基于间接平差原理,完成了间接平差软件设计,实现了导线网平差,以及导线网网形和误差椭圆的绘制,并通过实例进行了验证分析。Traverse network observation data adjustment is a tough task due to the complexalgorithm of matrix calculation , and there-fore it is difficult to use traditional programming language to realize the program and draw the error ellipse .Based on MATLAB plat-form, the paper uses its strong capacity of computation and visualization analysis function to achieve the parameter adjustment software design according to the parameter adjustment principle and the traverse network adjustment and shape , and drawing of error ellipse are realized and verified .
