永磁无刷电机MATLAB仿真模型，验证成功(Permanent magnet brushless motor MATLAB simulation model proved to be successful)

雷达数据显示与分析，包括雷达P显和E显两种方式，同时还可设置雷达量程、指定目标航迹数据显示等，该代码实用，值得参考。(Radar data and analysis, including radar and E P were significantly in two ways, but can also set the radar range, specify the target track data display, the code useful as reference.)

本文基于BP神经网络应用于预测的原理，提出预测步骤及预测可行性，探讨建立基于BP神经网络的预测模型的关键技术，包括样本的选取与预处理、输入输出变量的选取、隐层节点数的确定、初始权值和阈值的选取、激活函数、训练算法与参数的选取，最后建立合理的网络模型；结合住宅市场的实际情况，建立两类BP 神经网络预测模型：基于时间序列的趋势预测模型以及基于影响因素的回归预测模型，即分别采用神经网络趋势预测和回归预测的思路，把住宅市场的供给、需求与房价的历年数据以及其影响因素的数据分别作为学习样本，建立预测模型，进行预测。(Real estate development risk prediction )

自己编的APF，非常高效，谐波处理用的三单相分别滤波，值得下载(APF model produced by myself ，It’s very efficient)

NEURO-FUZZY BASED CONTROLLER FOR A SHUNT ACTIVE POWER FILTER

matlab图形图像书籍，对刚入门使用Matlab处理图像的同学帮助很大。(matlab graphics image books, great help to students who just started to use Matlab to process images.)

说明：  对音频信号进行短时自相关函数与短时平均幅度函数的计算，文件中包含MATLAB的GUI设计，可以自由更改窗长与选择帧，附有使用说明。(You can calculate the short-time autocorrelation function and the short-time average amplitude function of the audio signal with this program. I also design a MATLAB-GUI for it. The window length can be freely changed and the frame can be selected with instructions. Instructions for use are attached.)

采样定理 用来对模拟信号进行采样 使其变成数字信号 观察其频谱(Sampling theorem is used to carry out sampling of analog signals into digital signals so that it observe the spectrum)
