Matlab 通用神经网络代码；介绍说明以及源代码(General Matlab neural network code introductory notes, and source code)

利用MATLAB对神经网络进行编程,用newff()创建两层前向网络。网络输入范围[-1 1]，第一层有10个tansig神经元(using MATLAB right neural network programming with newff () to the creation of a two-tier network. Network input range [-1 1], the first layer 10 tansig neurons)

对信号进行内插处理，有16个复信号：1~16Hz；内插I=16 ；内插前采样率50Hz；滤波器265阶 。(Interpolation processing signal 16 multiplexed signals: 1 Hz to 16 Hz interpolated I = 16 before interpolation sampling rate of 50Hz filter 265 order.)

详细介绍了matlab与文件操作相关的语句用法(Detailed description of the matlab file operations associated with the usage of the phrase)

将含有高斯白噪声的输入信号通过线性系统后（带阻滤波器）的输入、输出前信号的频谱、功率谱对比。同时给出了线性系统特性(Gaussian white noise, containing the input signal by a linear system (bandstop filter) of the input, before the output signal spectrum, the power spectrum of contrast. Also gives a linear system characteristics)

说明：  通过状态空间方法建立了线性二自由度的车辆模型，然后通过转换，将状态空间转换成传递函数的形式，能看到速度变化后，质心侧偏角和横摆角速度的变化趋势。(The vehicle model with linear two degrees of freedom is established by the state space method, and then the state space is transformed into the form of transfer function through transformation. After the speed changes, the change trend of the sideslip angle and the yaw rate of the center of mass can be seen.)

说明：  本程序实现了RGB图像转化为灰度图像，而后对图像进行了二值化，比较适合初学者，因为很多复杂的程序初学者比较难理解，我写的这个程序可以作为入门程序。(This program realized RGB images to gray image, and then to the binary image.It is suitable for beginners, because many complicated procedure is difficult for beginners, I write this program can be used as introductory programs.)

机器人运动学和动力学模型，六自由度的，界面设计以及轨迹规划等功能(Robot kinematics and dynamics models, six degrees of freedom, interface design, and trajectory planning, etc.)

本程序仿真在给定系统延时下的QPSK系统误码率，其中没有使用成形滤波器，考虑了相位同步和符号同步，对工程人员很有参考价值(QPSK err rate simulation)

典型的MIMO链路级信道模型，可以参考使用，包括AWGN,信道参数设置，天线配置等(A typical MIMO channel link-level model, can refer to the use, including the AWGN, channel parameter settings, antenna configuration, etc.)
