运用matlab来实现了实时动画的一个示例(Use matlab to realize the real-time animation of an example)

说明：  此源码进行图片灰度值的处理，使图片更清晰，或者让其变成纯黑纯白(this code does the image gray level enhancement)

说明：  老外的电机学教材，最为重要的是有相应的MAtlab代码，每一章都有，十分详细，学习电机的必备工具书，文件是在太大，此处上传chap5的源码(Foreigners motor learning materials, the most important thing is there is a corresponding MAtlab code, each chapter has a very detailed study of the motor necessary books, documents are too large to upload chap5 source code here)

QPSK平方律定时同步算法实现定时误差和定时恢复(QPSK square timing synchronization algorithm ，estimate timing error and timing error correction )

用matlab设计FIR维纳滤波器 假设一个点目标在x，y平面上绕单位圆做圆周运动，由于外界干扰，其运动轨迹发生了偏移。其中，x方向的干扰为均值为0，方差为0.05的高斯噪声；y方向干扰为均值为0，方差为0.06的高斯噪声。用该滤波器处理观测信号，得到其最佳估计。(FIR Wiener filter design using matlab Suppose a point target in the x, y plane around the unit circle in a circular motion due to external interference, its trajectory shift occurred. Which, x the direction of the interference of mean 0 and variance of 0.05 Gaussian noise y direction of the disturbance is zero mean Gaussian noise variance 0.06. Observed with the filter processing signal, to get the best estimate.)

Rayleigh multipath/AWGN(Additive White Gaussian Noise) QPSK Gray used

MATLAB非常丰富的优化实验实例与讲解，附有源代码。(MATLAB optimization of very rich examples and explain the experiment with the source code.)

说明：  利用低通滤波器进行横条纹滤除，效果可以，最好进行一下后期处理，效果会更好。(Use of horizontal stripes of low pass filter filter, the effect can be desirable to look at post-processing, the effect will be better.)

基于非下采样小波变换的纹理图像特征提取程序(The sampling based on the wavelet transform of texture image feature extraction )
