1.边缘检测，分别用Sobel, Laplacian-Gaussian 方法对一幅灰度图像进行边缘提 取，并给出对比结果； 2.灰度阈值分割：利用双峰法对一幅灰度图像进行灰度分割处理。(1. Edge detection, respectively Sobel, Laplacian-Gaussian methods on a gray-scale image edge extraction, and gives comparative results 2. Gray threshold segmentation: Using Twin Peaks method a gray image gray-scale be dealt with separately.)

Amplitude Shift Keying Simulation

说明：  hurst指数估计 This function does dispersional analysis on a data series, then does a Matlab polyfit to a log-log plot to estimate the Hurst exponent of the series. This algorithm is far faster than a full-blown implementation of Hurst s algorithm. I got the idea from a 2000 PhD dissertation by Hendrik J Blok, and I make no guarantees whatsoever about the rigor of this approach or the accuracy of results. Use it at your own risk.

分析了BFSK的性能及原理，并利用matlab仿真实现其误码率等信息。写成word文档，后面附有源程序。(BFSK performance analysis and principle, and use matlab simulation to achieve its bit error rate information. Word document written in the back with a source.)

matlab的讲义，一些基础知识，语法知识等等(matlab lectures, some basic knowledge, grammar, etc.)

说明：  用随机数发生器产生二进制序列，他作为FSK调制器的输入。FSK调制器的输出受到概率a的加性高斯噪声污染，仿真得出系统的误码率。( Has the binary sequence with the random number generator, he takes FSK modulator s input. The FSK modulator s output receives probability the Canada Gauss noise pollution, the simulation obtains system s error rate. )

解决了三维数据可视化的问题；在三维网格点上数据绘制显示它的大小。 通过z轴坐标点更容易区分边缘颜色变化。可以通过设置线宽参数该选项设置为0。(This function solves the problem of visualization of 3 dimensional data in one plot(plot3). Data is plotted on a 3 dimensional mesh with point size showing value of it. Edge color changes via z axis to distinguish coordinate of points easier. That option can be turned off by setting the linewidth parameter to 0. )

这是一种整流电路，可以将相位相差120的三相交流电变换为直流，变化方法用到了电机控制中的坐标变换，SVPWM算法，方法比较新颖。(a kind of circuit which can convert three_phase AC voltage to DC voltge)
