该程序用CZT算法实现信号频率分析，并画出信号的波形图、FFT变换后的频谱图、CZT变换后的波形图(CZT transformer )

使用matlab中simulink仿真电机控制的初学者，可以看看(Matlab motor control simulation for beginners, you can download a look)

用于车牌识别，个人感觉比较好，大家可以看一下(For license plate recognition, personal feeling better, we can look at)

利用BP网络对非线性系统进行辨识，同时，利用模型参考自适应方法，设计NNMARC控制器(BP network identification of nonlinear systems, at the same time, the use of model reference adaptive method, design NNMARC controller)

基于高波滤波的特征提取技术，从而实现人脸识别和表情识别的目的(Based on high-wave filter feature extraction techniques, in order to achieve the purpose of face recognition and expression recognition)

用matlab编写的可控制速度得小球，可以激发学习GUI兴趣(Prepared using matlab to control the speed of a ball, you can stimulate interest in learning GUI)

说明：  matlab小波分解，将一幅图片分解为3次小波后再合成(matlab wavelet decomposition, will be a picture and then broken down into 3 wavelet synthesis)

说明：  条带式SAR的RD算法，里面参数可以自己设置(Of band SAR of the RD algorithm, which parameters can be set up their own)

Design and Use of Steerable Filters PAMI1991文章的代码，含有测试图像和demo，可运行(It implements a steerable Gaussian filter. This m-file can be used to evaluate the first directional derivative of an image, using the method outlined in: W. T. Freeman and E. H. Adelson, "The Design and Use of Steerable Filters", IEEE PAMI, 1991.)

电网谐波分析 用加汉明窗插值计算电网谐波频率 幅值 和相角。以快速傅里叶变化fft为基础(Harmonic analysis of power system using Hamming window interpolation calculation of the harmonic frequency amplitude and phase angle. The changes of FFT based on FFT)
