这是一个节点潮流计算算法程序，有兴趣的朋友可以看看(This is a node flow calculation algorithm, interested friends can see)

对于周期图的功率谱估计,当数据长度N太大时,谱曲线起伏加剧, 若N太小,谱的分辨率又不好,因此需要改进。两种改进的估计法是 平均周期图法和平滑平均周期图法。Bartlett法:Bartlett平均周期图 的方法是将N点的有限长序列x(n)分段求周期图再平均。(For the power spectrum estimation of the periodogram, when the data length N is too large, the spectral curve fluctuation intensifies,   If N is too small, the spectral resolution is not good, so need to be improved. The two improved estimates are   Average Period Graph and Smooth Mean Period Graph. Bartlett method: Bartlett average cycle chart   Is to re-average the finite-length sequence x (n) of N points by periodogram.)

前向反馈BP神经网络算法matlab源程序，有详细的注释，是学习编写程序的基本例程。(Feedback prior to the BP neural network algorithm matlab source code, there are detailed notes, is to learn the basic programming routines.)

车间布局的主程序，这个程序对车间布局问题具有普遍通用性。(Plant layout of the main program, a program of facility layout problems with general versatility.)

说明：  此程序是变型PID控制算法的仿真程序，采用了变速积分方法，系统偏差大时，积分作用应减小，反之应加强。变速积分可以根据系统误差大小改变积分速度，提高了系统品质。(this procedure is a change in the PID control algorithm simulation program using the variable integration method, the system deviation, the integral role should be reduced, on the contrary should be strengthened. Integral variable speed system error can change the size of integration of speed, quality of the system.)

基于深度学习的稀疏自编码器，对图像特征进行提取，然后分类(Extraction the encoder based on sparse feature depth study)

◆输入数据： 由键盘输入待查文本文件名和待查单词。待查文件名为：input.txt。 ◆输出数据： 输出文件为output.txt，该文件第一行为该单词在文件中出现的次数。 从每二行开始是依先后次序输出的包含该单词的句子。 (◆ Input data: text file name to be examined by the keyboard input and searching words. Unknown origin file name: input.txt. ◆ Output data: output file output.txt, the first acts of the file of the word the number of occurrences in the document. From the beginning of every second line is output in the order in which the word sentences.)

一些用matlab编的经济学程序，都是很经典的一些程序(Matlab made some use of economics procedures are some of the classic procedure)
