主元分析（PCA）的Matlab源代码分析(source code of PCA runed on Matlab)

二维空间中的多边形逼近。确定三个顶点a，b，c并且其函数值按从小到大排列。将二维空间中的多边形三个顶点的函数值按从小到大顺序排列， 判断三点或三点函数值的距离是否小于给定阈值.若小于阈值停止循环，得最优解x0=a(Two-dimensional space polygon approximation. Determine the three vertices a, b, c and its function value in ascending order. The three-dimensional space polygon vertices function values ​ ​ in ascending order, function to determine the three o' clock or three values ​ ​ of the distance is less than a given threshold and if less than the threshold value to stop loop, get the best solution x0 = a)
