mat lab code .. applying pca on any matrix of matlab. feature vector will give the featuevector change the dimentional matrix

在matlab里面，构造三次样条插值函数s(x)来模拟一只飞鸟外形的上部，根据已知的测试数据。(In matlab inside, construct cubic spline interpolation function s (x) to simulate the shape of the upper part of a bird, according to the known test data.)

说明：  计算附加条件的二阶二元偏微分方程组的程序，使用四阶龙格库塔方法。工程上有重大应用。(Calculate conditional second-order partial differential equations of two yuan, the use of fourth-order Runge-Kutta methods. Significant engineering applications.)

用MATLAB求复杂网络整体的平均路径长度，度分布，聚类系数(average path length of the complex neetwork)

多目标优化 相对传统多目标优化方法, PSO在求解多目标问题上具有很大优势。首先, PSO的高效搜索能力有利于得到多目标意义下的最优解 其次, PSO通过代表整个解集的种群按内在的并行方式同时搜索多个非劣解,因此容易搜索到多个Pareto 最优解 再则, PSO的通用性使其适合于处理所有类型的目标函数和约束 另外, PSO 很容易与传统方法相结合,进而提出解决特定问题的高效方法。就PSO 本身而言,为了更好地解决多目标优化问题,必须解决全局最优粒子和个体最优粒子的选择问题(Compared with the traditional multi-objective optimization of multi-objective optimization method, PSO in solving multi-objective problem has a great advantage. First, PSO is conducive to the efficient search capabilities are more objective sense of the optimal solution Secondly, PSO representative of the entire solution set through the population by way of the inherent parallel search multiple non-inferior solution, and this can easily search for the most number of Pareto optimal solution Furthermore, PSO' s versatility make it suitable for handling all types of objective function and constraints addition, PSO is easy to integrate with the traditional method, and then propose an efficient way to solve specific problems. The PSO itself, in order to better address the multi-objective optimization problems, the need to address the global best particle and the individual selection of the optimal particle)
