在讨论多项式趋势面分析时,作者采取程序技巧,用保留全过程用到的中间结果的方法,协调法方程系数阵和常数项快速生成的关系,收到很好的效果。同样的方法,也用干趋势值计算。文中还讨论了以一组标准模块组成的复杂测网以方便数据准备的问题。
When discussing polynomial trend surface analysis, the author adopts the procedural skills and uses the method of preserving the intermediate results used in the whole process to coordinate the relationship between the coefficient matrix of the normal equation and the constant term, and receives very good results. The same method is also used to calculate the dry trend value. The article also discusses the complex network with a standard set of modules to facilitate data preparation.
