说明：  利用matlab求解线性规划与非线性规划(Using matlab for solving linear programming and nonlinear programming)

The code displays the complexion of a person from his or her image.

说明：  进退法是用来确定搜索区间（包含极小点的区间）的算法，其理论依据为：f(x) 为单谷函数（只有一个极小值），且[a,b]为其极小点的一个搜索区间，对于任意x1,x2∈[a,b] ，如果f(x1)<f(x2)，则[a,x2]为极小点的搜索区间，如果f(x1)>f(x2) ，则[x1,b] 为极小点的搜索区间。黄金分割求极值(In a method is used to determine the search interval (contain minimum point interval) algorithm)

切割方体的最优算法，用动态归划 Mathematica程序(The superior calculate way that incises a square body returns to row with the dynamic state)
