This code can be use in fresnelzone of seismic data.

小波分析因其在处理非平稳信号中的独特优势而成为信号处理中的一个重要研究方向。如今随着小波理论体系的不断完善，小波以其时频局部化特性与多尺度特性在图像边缘检测领域中倍受青睐。(Wavelet analysis of nonstationary signal processing because of its unique advantage in signal processing and become an important research direction in. Now with the wavelet theory system ceaseless and perfect, the time-frequency localization characteristic of wavelet based and multi scale characteristics in the image edge detection is very popular.)

采用分层的前推回代法应用于n节点的电力系统，收敛速度快，准确度高，电力系统配电网潮流计算。(Layered forward and backward substitution method used in the power system of n nodes, the convergence speed, accuracy, power system with the power flow calculation.)

说明：  mylsb.m是个非常完整的LSB密写源码并且密写和提取都在里面，图片我没上传，你只需要添加一个图片文件就可以了，记住图片必须是灰度图片，如果是RGB，我转换的代码也在里面很有意思哦。weipingmian.m是个提取图像位平面的程序，图片也是需要你自己加载，最后一个就是8*8块的图像DCT变换。(mylsb.m is a very complete source of LSB Steganography Steganography and extraction, and are on the inside, I did not upload pictures, you only need to add a picture file on it, remember the image must be a grayscale image, if it is RGB, I converted the code is also very interesting inside Oh. weipingmian.m is a program to extract bit-plane images, pictures, you also need to load the last one is 8* 8 DCT transformed image.)

2D Fourier变换在光衍射方面的应用一例,对孔函数直接应用FFT2,得到衍射结果；以及FDTD方面的两个不成熟的程序(2D Fourier Transform-ray diffraction case of the application of direct application Kong FFT2 function, be diffraction; FDTD and the two immature procedures)

使用matlab，绘画出美国的星条旗。请运行main文件(use Matlab, painting the stars and the United States. Please operation main document)

matlab code for ml detection in networks

正对电机双闭环的系统调试的matlab中simulink仿真模型(Is the double closed loop system debugging of motor in the matlab simulink simulation model)

可以实现条形图和阶梯图形，导入marlab中很容易实现(picture of strip and ladder)
