我的数字信号处理课程设计，感觉做的一般。(My digital signal processing curriculum design, make the general feeling.)

How to solve ODE in matlab

说明：  matlab神经网络工具箱分析设计(Matlab Toolbox neural network analysis and design)

利用smith圆图演示射频电路匹配过程，参数可调，界面良好。(Smith chart shows the use of RF matching process, adjustable parameters, the interface is good.)

添加wav文件或者录音 实现频谱分析 是个MATLAB文件(Add wav files or recording to achieve spectral analysis)

PHOTOVOLTAIC MODELISATION WITH SIMULINK

Matlab 批量读写txt文件，打开文件夹里面所有的txt文件 然后进行运算 保存为其他格式的文件， 如dat 已调试，能够运行(Matlab batch literacy txt file, open the folder inside all the txt file and then save operation documents to other formats, such as dat has been debugged, to run)

实现butterworth滤波器,能够输出幅频特性曲线(Realize Butterworth filter, to output the amplitude-frequency characteristic curve)

Matlab快捷键命令大全，感觉很有用，希望大家喜欢！！(Matlab shortcut command Guinness, feel useful, I hope you like it! !)

介绍了坐标变换在异步电机中的应用条件和原则，以便能够快速地在异步电机中选择合适的坐标，提高工作效率．并结合异步电机矢量控制存MT坐标系中变换后，可类似于直流电机的转矩电流分量和磁场电流分量(the vector control of asynchronous motor based on the right coordinate)
