傅立叶变化的Matlab实现，对于学习FFT非常有帮助。FFT文件夹内有多个程序。(Matlab Fourier realize change, for learning FFT very helpful. FFT folder has a number of procedures.)

Quaternion library for inertial navigation system

深海声道声线图绘制程序，仿真绘制深海声传播图形；并设计了可更改参数的图表及清零功能。(Deepwater channel sound line drawing program, drawing deep sea sound propagation simulation graphics and designed charts and clear function can change the parameters.)

数字图像处理中 灰度处理函数 如果有需要的请下载 谢谢了 (Gray-scale digital image processing function to)

二维TM模电磁波FDTD仿真，UPML边界(2D TM electromagnetic FDTD simulation, UPML border)

模拟退火算法来源于固体退火原理，将固体加温至充分高，再让其徐徐冷却，加温时，固体内部粒子随温升变为无序状，内能增大，而徐徐冷却时粒子渐趋有序，在每个温度都达到平衡态，最后在常温时达到基态，内能减为最小。 (Simulated annealing algorithm derived from solid annealing principle, the solid is heated to a sufficiently high, let it cool slowly, when heated, solid particles with temperature becomes disordered state, the internal energy increases, while slowly cooling the particles gradually increasingly ordered at each temperature to reach equilibrium, and finally reach the ground state at normal temperature, which can be reduced to a minimum.)

这个是一个排序熵的程序，它能够达到信息熵的目的，算是一个改进的方法。应用起来比较方便(This program is a sort of entropy, it can achieve the purpose of information entropy can be regarded as an improved method. Was easier to apply)

实现坐标点的旋转，先将坐标移到以坐标系原点为圆心的坐标系中。(To achieve the rotation of the coordinate points。)

可以识别二维的条形码。读入条形码图像之后即可处理成相应的数字。但是对图像存储位置有要求，所以请按照程序前面的存储位置放置您的二维图像(Can identify the two-dimensional barcode. Reads the barcode image can be processed into a corresponding digital. But the image storage location requirements, so please be placed in accordance with the storage location of the program in front of the two-dimensional image)
