摘　　要：针对测量平差烦琐的矩阵运算问题,本文利用矩阵实验室(matrix laboratory,MATLAB)平台进行水准网平差、精度评价与可视化展示。由于间接平差误差方程式建立的规律性很强,而条件平差的条件方程式的规律不够明显,本文根据间接平差的原理进行程序设计并进行实例验证,实现了水准网间接平差的程序化及可视化表达,该程序的设计与可视化界面的设计降低了误差出现的概率,极大提高了水准网平差及精度评价的速度和精度,可应用于水准网间接平差的计算中。In view of the complicated matrix operation problem of measurement adjustment,this paper applied Matlab platform to carry out leveling net adjustment,precision evaluation and visual display.Because the indirect adjustment error equation established regularity is very strong,and the law of the adjustment of condition equations is not obvious,in this paper,based on the principle of indirect adjustment for program design and verified instance,the leveling network indirect adjustment and stylized visual expression,the program design and visual interface design were implemented to reduce the probability of errors,which greatly improved the speed and precision of leveling net adjustment and accuracy evaluation,and can be used in the calculation of leveling net indirect adjustment.
