对轴承模拟信号进行解调分析,轴承模型见毕果博士论文（3-14），（3-29）；(A demo of demodulation of gear simulation signal)

BB method of Hestogram equalization BBHE

本程序用通过归一化的方法来实现sobe1算法，是sobel的边缘检测算法的具体实现。(The procedure used by one of the method to implement sobe1 algorithm is sobel the edge of the realization of the detection algorithms. )

这是我自己写的亲测可用的matlab 牛顿迭代法函数程序(This is the Newton iteration program based on MATLAB written by myself)

matlab插值与拟合，有PPT演示功能，还有相应源码文件(matlab interpolation and fitting, with PPT presentation capabilities, as well as the corresponding source file)

Reflective semiconductor optical amplifier

说明：  对信号进行小波变换，确定小波基的选择和分解层数，再求解信号的信息熵，可用于故障诊断。(The wavelet transform is performed on the signal to determine the selection and decomposition layers of the wavelet base, and then the information entropy of the signal is solved, which can be used for fault diagnosis.)

这是解微分方程的经典matlab程序包，里面包含的内容比较多，大家可以选择自己需要的用(This is the classic solution of differential equations matlab package, which contains more, everyone can choose their own need to use)

图像的平面微分平方和能够反映图像高频分 量的能量。用计算平面微分平方和的方法在空间域上计算相邻像素亮度差值的平方和，对应于在频率域上计算图像高频分量的能量和，此值越大，图像对焦越准确(Differential square image plane and the image can reflect the energy of high frequency. Computational method of Planar Differential squares calculated in the space domain to the square of the difference between the brightness of adjacent pixels and corresponds to the image in the frequency domain calculation of high frequency energy and, this value is larger, the more accurate the image focus)

刚注册，第一次发，学习学习。 利用matlab仿真2fsk(Just registered, the first hair, learning to learn. 2FSK simulation using matlab)
