中文说明：模拟了一个裂隙生成文件，以及删除多余的方法，这里给出分形插值曲面的计算公式，对该方法在MATLAB中实现化学元素曲面的L次逼近进行了研究和探讨，给出了实现的算法步骤。编制了相应的MATLAB程序，并将该程序应用于实际成矿测区——西藏自治区贡觉县各贡弄工作区化学元素的分形插值曲面构造。从整个实现过程可以充分体会MATLAB在解决实际问题上的方便性和高效性。
English Description：
This paper simulates a crack generation file and the method of deleting superfluous, & lt; span style = & quot; color: # font- family:Arial , "font- size:13px;background-color In this paper, the calculation formula of fractal interpolation surface is given, the L-th approximation of chemical element surface in MATLAB is studied and discussed, and the algorithm steps are given. The corresponding matlab program is compiled and applied to the fractal interpolation surface construction of chemical elements in Gongnong working area, Gongjue County, Tibet Autonomous Region. From the whole implementation process, we can fully understand the convenience and efficiency of MATLAB in solving practical problems.
