摘　　要：主要介绍了Matlab语言和水准高程拟合的相关理论及精度评定方法,并以某海岸带为算例背景,结合几种不同组合方案,利用Matlab编程语言分别计算了平面拟合与二次曲面拟合的检核结果,并进行了精度分析与评定,得出拟合误差对高程拟合精度影响的相关因素。This paper mainly introduces the related theories and accuracy evaluation methods of Matlab language and leveling elevation fitting. Taking a coastal zone as the background of an example,and considering several different combination schemes,the test results of plane fitting and quadric surface fitting are calculated using Malab programming language. The relevant factors of the influence of the fitting error on the elevation fitting accuracy are obtained.
