这是一个matlab的gui视图设计小程序，用matlab制作的计算器，对帮助学习很有好处(This is a matlab gui view of the design of small programs produced using matlab calculator to help learning is very good)

Matlab中所有的内部函数，学习后能够全览matlab中的函数。(Matlab, all internal functions, learning later to be fully in relation to the function of matlab.)

说明：  假如数据中有N 个变量，而我们想抽取的样本的数量是M,那么在对数据进行抽样的时候，这种方法首先会把N个变量的设计空间均匀的划分开为M份，然后在每个划分好的区域中随机的抽取一点，最后，从这M个变量里，随机挑选之前选好的点，构成我们的样本(If there are n variables in the data, and the number of samples we want to extract is m, then when sampling the data, this method will first divide the design space of n variables into M parts evenly, and then randomly extract a point in each divided area. Finally, from the m variables, randomly select the previously selected points to form our sample)

说明：  基于德洛内三角分解的有限元划分，可形成刚度总阵(Delaunay triangulation based on decomposition of the finite element division, the total stiffness matrix can be formed)

模糊聚类和数据分析工具箱是一个集合的Matlab功能。它的提出​ ​ 是将一个给定的数据集为子集（称为集群），硬和模糊分区的意思是，这些之间的转换子集是脆的或渐进的。(The Fuzzy Clustering and Data Analysis Toolbox is a collection of Matlab functions. Its propose is to divide a given data set into subsets (called clusters), hard and fuzzy partitioning mean, that these transitions between the subsets are crisp or gradual.)
