运用MATLAB计算机编程按照分块分形插值方法对农业地形数据进行了处理。该方法通过对地质采集数据进行分块分形插值,较好地根据少量数据拟合地形并可以借助此法对地形数据进行定量分析。同时,在此基础上进一步探讨了运用此法具体所得预测数据与实际数据相比较,证实其数学模型的可靠性,发现对地形数据的处理是相当精确的。由于这种方法对于具有自相似性的地形地貌特征具有简单可行的特点,且便于运用简单的MATLAB程序实现,因此较易得到有效的推广。
In the paper, the application of piecewise fractal interpolation to topographical using MATLAB program is introduced. This method based on the principle of piecewise fractal interpolation can deal with the topographical data, and the processing result is good. The example shows that the method is simple and easy to apply. The method of after test residue checking shows the effect of the way is better and the error is limited. The method can be emulated bv MATLAB programmed simply, so it will be used'widely.
