混沌保密通信SIMULINK建模模。自己作的很好的东西。 (Chaotic secure communication SIMULINK modeling mold. As a good thing.)

对融合图片质量的评价指标，包括峰值信噪比和均方根误差,非常好用(the ution index of image fusion.include PSNR and RMSE ,it is very useful)

to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution now compare our special 8X8 functions with the internal general functions use this code: A = int32(100*rand(8,8)) tic for i = 1 : 1000 IDCT_8X8(DCT_8X8(A)) end toc tic for i = 1 : 1000 idct2(dct2(A)) end toc i had built the general functions too, but with low speed (to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expressionfor M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the executionnow compare our special 8X8 functions with the internal general functionsuse this code: A = int32 (100* rand (8,8)) tic for i = 1: 1000 IDCT_8X8 (DCT_8X8 (A)) end toc tic for i = 1: 1000 idct2 (dct2 (A)) end toc i had built the general functions too, but with low speed)

模糊控制器，能够实现模糊控制，自适应迷糊控制(Fuzzy Control)

QPSK信号通过Rayleigh信道，并计算出误码率(QPSK signals go through Rayleigh channel)

对海浪数据处理得到海浪谱。可以模拟不同风速产生的海浪谱，并得到一维海面分布。(Propose the wave hight data and spectrum analysis.Wave spectrum generated by different wind speeds can be simulated and one-dimensional sea surface distribution can be obtained.)

基于动态规划的生产储备问题的matlab程序和调用程序(Production of reserves based on dynamic programming problem matlab procedures and the calling program)

Generate mesh for finite element

matlab 中用Bisection方法求解一元多次方程，是一种很好的算法。但收敛速度比较慢，是线性收敛(matlab using Bisection method for solving multiple equations one yuan, is a good algorithm. But convergence is slow, linear convergence)

（1） 使用录音软件或者Matlab函数，分别采集一段浊音和清音语音信号（是你自己说的，如：a，o，s等），采样率为8KHz，量化精度为16比特线性码，存在自己指定的目录下，例如D盘根目录下叫sound的文件夹中，录音文件名为yourfilename_a.wav，yourfilename_s.wav等。录音的软件和Matlab函数的使用见随后的附录。 （2） 根据语音信号的短时平稳特性，分析帧长取30ms（或10ms～50ms）； （3） 利用上述基音提取的三种方法（任选两种方法）的编程流程图（图1、图2和图3）编制浊音语音基音提取的matlab程序，上机调试给出相应波形，并根据图形，分析计算出基音周期。所用公式为： (1.5) 其中 是基音脉冲处所对应的位置， 是抽样频率， 是基音周期。 （4） 将语音信号换为清音语音，运行程序，与浊音语音的运行结果进行比较，并得出结论。 ( voice signal processing)
