输出量通过回路使得占空比D增加或减少，以控制电压的输出或减少，从而达到最大功率点(Output circuit by which the duty ratio D is increased or decreased to reduce the output or control voltage to achieve maximum power point)

采用matlab进行语音处理的软件包，如分帧，求语音特征等。(Using matlab package deal for voice, such as sub-frames, and voice characteristics.)

Matlab圆弧插补，只要给定起点与终点，半径，设点圆心方向以及顺逆时针方向即可实现插补(Matlab circular interpolation, given the starting point and end point, radius, set the direction of the point of the center as well as Shun counterclockwise to achieve interpolation)

基于压缩感知理论的recPF重构算法,recpf为最新的重构算法，比之前omp之类算法，效果更好(Based on the theory of compressed sensing reconstruction algorithm recPF )

旅行商问题，即TSP问题（Travelling Salesman Problem）又译为旅行推销员问题、货郎担问题，是数学领域中著名问题之一。假设有一个旅行商人要拜访n个城市，他必须选择所要走的路径，路径的限制是每个城市只能拜访一次，而且最后要回到原来出发的城市。路径的选择目标是要求得的路径路程为所有路径之中的最小值。(Traveling Salesman Problem, or TSP problem (Travelling Salesman Problem) also translated as the traveling salesman problem, traveling salesman problem is one of the well-known problems in the field of mathematics. Suppose you have a travel business to visit n cities, he must choose which path to go, limiting the path is to visit each city only once, and the last to return to the original departure city. Select the destination path is the requirement for the minimum distance path was among all paths.)

精通MATLAB参考源码第九章，喜欢MATLAB和神经网络的可以好好学习下，绝对的好资源！(Chapter IX proficient MATLAB reference source, like MATLAB and neural networks can learn, the absolute good resource!)

说明：  将pca和elman神经网络结合起来，找到了主要的变量(The PCA and the Elman neural network to combine to find the main variables)
