数值计算实践是我们必备的一门学科！这是我在学习之余利用MATLAB编写的程序，希望对大家有用！(Practice of numerical calculation is that we must have a subject! This is what I learn and use in the preparation of procedures for MATLAB, in the hope that useful!)

本程产生了二进制相位调制脉冲压缩信号，在mimo雷达信号编码中有所应用(This process produces a binary phase modulation pulse compression signal mimo radar signal coding has been applied)

基于小波变换神经网络的车流量预测，含程序和数据。小波分析是针对傅里叶变换的不足发展来的，傅里叶变换是信号处理领域中应用最广泛的的一种分析手段，然而它有一个严重不足，就是在变换是抛弃了时间信息，变换结果无法判断某个信号发生的时间，即傅里叶变化在时域中没有分辨能力。小波是一种长度有限，平均值为0的波形，它的特点包括：（1）时域都具有紧支集或近似紧支集；（2）直流分量为零。小波函数是由一个母小波函数经过平移与尺寸伸缩得到，小波分析即把信号分解成一系列小波函数的叠加。(Vehicle flow prediction based on wavelet transform neural network)

基于MATLAB的计算机控制系统，PID控制器的PI控制仿真分析。(Based on the MATLAB computer control system, PID controller PI control simulation analysis.)

说明：  这个程序根据训练好的网络文件ANN.mat预测新的数据文件，得到均方误差，并画出预测数据和原数据的对比图。此程序运用到了很多Matlab编程中常用到的表达方式，还有一些神经网络编程的基本概念的表达，如归一化的表达。希望能对大家有所帮助(This program the trained network file ANN.mat predict new data file, get the mean square error, and forecast data and the original data to draw the comparison chart. This procedure applied to a lot of Matlab programming to the expression commonly used, there are some basic concepts of neural network programming expression, as normalized expression. Hope you can help)

This model is to determine the number of solar panels needed and the minimum battery capacity needed(in amps)and also for the required backup time
