文章描述的是如何使用matlab设计一个可视化的界面，其中很详细的描述了每一步应该如何操作，具有不错的借鉴意义。(The article describes how to use matlab to design a visual interface, which is described in great detail how each step should be, with a good reference.)

⑴.设计游乐平面图，所含景点不少于10个。以图中顶点表示游乐园各景点，存放景点名称、代号、等信息；以边表示路径，存放路径长度等相关信息。 ⑵．为游人提供图中任意景点的问路查询，及查询任意两个景点之间的一条最短的简单路径。 (⑴. Designed to play plan, contained less than 10 scenic spots. To graph vertices, said the amusement park attractions, attractions store names, codes, and other information to edges, said path, the path length of storage of information. ⑵. To provide the figure for the visitors ask for directions any spots, queries, and query any two attractions of a shortest simple path.)

说明：  压缩包里包含了无约束优化问题常用的几种求解方法的源程序：变量轮换法（variable_rotation.m）、最速下降法（steepest_descent.m）、修正牛顿法（modified_newton.m）、共轭梯度法（conjugate_gradient.m）。另外，coefficient_matrix.m为目标函数系数获得矩阵，minval.m为最小值计算函数，gradient.m为梯度计算函数(Compression bag contains unconstrained optimization problems of several commonly used method of source: variable rotation Act (variable_rotation.m), steepest descent method (steepest_descent.m), as amended Newton (modified_newton.m), conjugate gradient method (conjugate_gradient.m). In addition, coefficient_matrix.m as the objective function coefficients obtained matrix, minval.m function for the minimum calculation, gradient.m for gradient calculation function)
