[原创]自己写的mallat算法matlab源程序，完全按照教材定义编写，有助于深入理解mallat小波变换。([Original] wrote it myself Mallat algorithm matlab source code, in full accordance with the definition of the preparation of teaching materials, contribute to better understanding of Mallat wavelet transform.)

FFT数字滤波源代码，和DSP的MATLAB实现相辅相成(FFT digital filtering, source code, and to achieve complementarity DSP-MATLAB)

this file give different codes of modulation

对于雷诺方程的求解和绘制滑动轴承的压力分布图，自带测试数据，点击可运行(a kind of solution of reynolds equation and the picture of pressure )

NSD检测边缘算子，可用于一维信号二维图像，检测阶跃边缘(NSD edge detection operator, the signal can be used for one-dimensional two-dimensional image, the edge detection step)

这三个小程序都是matlab的.m文件，分别实现用灰度变换的方法增强图像的对比度和直方图均匀化，模拟图像受高斯白噪声和椒盐噪声的影响。(The three procedures are Matlab. M documents, were used to achieve gray transform method to enhance the contrast of the image and histogram equalization. Simulation images by white Gaussian noise and the noise of Salt and Pepper.)

说明：  esn代码，稍加修改，不一定正确，上传分享(The modified ESN code is not necessarily correct. Upload and share the code.)

matlab实现的区域增长和分水岭算法，以及基于sobel算子，prewitt算子，canny算子，log算子的边缘检测算法。(matlab implementation of regional growth and watershed algorithm, and on the sobel operator, prewitt operator, canny operator, log operator edge detection algorithm.)

matlab数字图像矩阵的现实及傅里叶变换matlab digital image matrix of reality and the Fourier transform(matlab digital image matrix of reality and the Fourier transform matlab digital image matrix of reality and the Fourier transform)

大学时候跟导师做的一个暂态电磁场数据分析的程序，用于自动检测和识别波形数据中的脉冲起始时间等参数(University instructors often do with a transient electromagnetic field data analysis procedures, for the automatic detection and identification of waveform data pulse parameters, such as start-up time)
