【摘要】 由于在工程上只能得到一些离散数据,所以在面积的计算上就显得十分复杂,尤其当边界是不规则曲线时。这里提出一种基于MATLAB语言的简单、可行的计算方法,并对该方法的原理、算法、精度分析作了详细的阐述。通过模拟实验数据的计算和分析,说明该方法计算面积的精度较高。另外,所给程序还能绘出工程上需要的边界图形。更多还原

【Abstract】 In engineering the computing of an area is very complex because of a few discrete data being available when the curve of bounder is irregular. In the paper a simple and practicable approach is introduced to deal with this difficulty and meanwhile, it’s principle, the algorithm and precision analysis are expatiated. The results of numerical experiments verify the precision of the method. Moreover, the programmers can also give the graphs of boundaries.更多还原
