matlab实现二维数组的fft变化，得到时域图、幅频域图。(fft change implementation, time domain, frequency domain amplitude, is a two-dimensional array of the FFT changes)

说明：  简单的爬虫程序，可以用来爬取网页信息，基于python实现(Simple crawler program)

说明：   使用二分法对样本集进行剪辑，剪辑法的思想，就是将样本集分成训练集与考试集， 利用训练集样本对考试集的样本进行分类（使用近邻法），如果考试集中某个样本分类错误的话，将这个样本删除。在该函数中，使用最近邻法，只进行一次剪辑（遍历完考试集中的样本以后退出）。还有一种重复剪辑法（适用于样本比较多的情况），把样本随机分为多个样本集，将相邻的两个样本前一个作为考试集，后一个作为训练集，调用二分剪辑。所有的样本子集剪辑完毕以后，在递归调用，直到没有样本被剪辑掉,没得讲，重复剪辑的效果肯定好一些。 (The sample sets using the dichotomy of the clips, editing law idea is to sample set into training set and test set, using the training set samples to the test set of samples (using the nearest neighbor algorithm), if the examination focused on a sample of classification error then delete this sample. In the function, use the nearest neighbor method, only once clips (focused on a sample of traversal finished after the exit exam). There is also a repeat clip method (samples are more applicable to the case), the samples were randomly divided into multiple sample set, the two adjacent samples of the former one as a test set, the latter one as a training set, call the two sub-clips. All the samples were a subset of the clips after they have finished, in the recursive call, until there are no samples were clip out, did not have to say that the effect of repeated clips definitely better.)

电动汽车燃料电池simulink仿真模型，用于电动汽车或者混合动力汽车的仿真模型(Simulink simulation model of the electric vehicles fuel cells for electric vehicle or hybrid vehicle simulation model)

it is rvm matlab code

该代码基于灰色GM(1,1)算法，使用时，需要在函数中将自变量取为时间序列，可预测任意时间的数值(The code is based on gray GM (1,1) algorithm, when used in the function argument will be taken as time series, can predict the value of any time)

this matlab code denoise the pink noise from pcg signal and generate the specogram

说明：  求网络图中各节点的度及度的分布曲线， 聚类系数及整个网络的聚类系数，和复杂网络中两节点的距离以及平均路径长度(Find the degree and degree distribution curve of each node in the network graph, the clustering coefficient and the clustering coefficient of the whole network, the distance between two nodes in the complex network and the average path length)
