Crypto graphy matlab coding

说明：  DSSS is the source code to generate the following things

说明：  该代码为灰度投影算法进行两帧图像的匹配及配准的代码(The code for the gray projection algorithm and the two images match registration code)

说明：  最近看到有人提问怎样用FFT实现频谱分析，我认为能够进行到频谱分析的人，对于系统研究的深度基本上已经相当不错了。本人今天做了一个例程，发给大家参考一下。 历程主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。(The question was asked recently to see the realization of how to use FFT spectral analysis, I think that spectral analysis can be carried out to those who study the depth of the system basically is already quite good. Today I made a routine, distributed to Members for reference. The main contents of the course (signal_analyzer.rar) are as follows: test1.txt the first time as t, 0.001s for the step the second as the system input signal the third as a system output signal. signal_analyzer.m first test1.txt data read into workspace, and then proceed to FFT, analysis of the two signal frequency, output amplitude for input attenuation (db), the output of the input phase difference.)

粒子群搜索的matlab程序，对于一个隐函数寻优，四维隐含数嵌入在子函数中，可根据需要更改，(PSO Matlab search procedures, an implicit function optimization, 4D implied several embedded in the Functions, may need to change.)

这里介绍了VC与matlab的简单联合运用，初步学会结合(Here are the simple joint use of the VC and Matlab, initially learned to combine)

信号的幅度调制和连续信号的Fourier变换(Amplitude modulation and Fourier transform continuous signals)

在线向量回归分析，有包涵一个例子和内定函数等(On-line vector regression analysis, there is an example of indulgence and unofficially functions, etc.)

本文详细介绍了如何实现VC与Matlab的混合编程，对于进行复杂的运算有很好的用处(This paper describes how the VC and Matlab programming mix, for complex calculations to good use)

说明：  仿真入射到理想导体平板的情形，边界为PML吸收边界，观察电磁波反射过程(Simulate the case of incident to the ideal conductor plate, the boundary is PML absorption boundary, observe the electromagnetic wave reflection process)
