BP_PID

汽车七自由度改编的振动程序，采用对比方法比较了《汽车振动分析》里面的振动程序，欢迎大家下载学习与交流(vibration of the car with seven degrees)

说明：  这是一些滤波的小程序,用MATLAB编的,没有用到MATLAB自身的一些函数(This is a small number of filtering procedures, using MATLAB series, did not use its own MATLAB some function)

《matlab神经网络43个案例分析》源码27，BP神经网络的预测——人脸识别 ( Matlab neural network 43 Case Studies Source 27, BP neural network prediction- Face Recognition)

说明：  针对差分进化( DE) 算法后期收敛速度变慢、收敛精度变低以及易陷入局部最优解的缺点，提出一种基于双种群自适应进化的改进差分进化算法。(To overcome the shortcomings of slow convergence speed, low convergence accuracy and easy to fall into local optimal solution of differential evolution (DE) algorithm, a new algorithm is proposed. An improved differential evolution algorithm for adaptive evolution of two populations.)

说明：  三种子波函数，sinc函数 正弦函数 Riker函数还有有限差分介质设定(Third seed wave function, sinc function, sine function has finite difference Riker media set)

双向渐进结构拓扑优化原始代码，采用软杀伤法的BESO( the source code of Bidirectional evolutionary structural topology optimization with the soft kill law BESO)

说明：  基于MATLAB的编程，很好很强大。对于信道仿真非常有用(MATLAB-based programming, very very powerful. Channel simulation is very useful for)

matlab的降维工具箱 从官网上下载的(Dimensionality reduction downloaded the official website matlab toolbox)

LTE上行链路仿真C代码,包含CRC添加、信道编码、信号调制、基带信号等~(LTE simulation for the uplink of C code, including CRC added, channel coding, modulation, baseband signal. )
