histogram equalization in matlab

MFSK modulation is for underwater acoustic communication

此为本人matlab学习笔记，从入门开始，手把手教你学会(the matlab self study)

利用matlab实现无约束优化，对不同的函数进行优化，并比较优化结果和运算速度(Matlab unconstrained optimization, optimize and compare different function optimization results and computational speed.)

本程序生成的图片容量大概3M左右，所以对计算机配置要求较高。(This program generates pictures capacity probably about 3M, so the higher the computer configuration requirements.)

this coding use for students who use matlab steganography. the code will be highly used in recent times.

SVM非线性分类，数据与代码均给出，而且还有结果图列，望能给予帮助(SVM linear classification, data and code are given, but also the results of figure out, hope for help)

摘要:为提高密码的抗攻击性,利用超混沌系统随机性好!可确定再生,且密钥空间较大的特性,提出了一种基于四维连续超混沌系统和扩展映射的实时视频流加密算法"(Abstract: In order to improve the password anti-aggressive use of system randomness hyperchaos good! Regeneration can be identified, and key characteristics of the larger space, a row based on four-dimensional hyperchaotic system and expansion of mapping real-time video stream encryption algorithm )

频域SCOT自适应时延估计，实质上是对广义功率频函数平方得到的数的相位谱做最小二乘拟合，求得时延估计。(Frequency domain SCOT adaptive time delay estimation, is essentially the generalized power-frequency phase of the function of the square of the number spectrum of the least squares fitting obtained delay estimates.)

Code to obtain the filtering function polynomials F(s), E(s) and P(s), and the constants eps and eps_r from transmission zeros, with Cameron s method.
