说明：   模拟退火算法求函数 f(x)的最小值点， 且 l <= x <= u f为待求函数，x0为初值点，l，u分别为搜索区间的上下限，kmax为最大迭代次数 q为退火因子，TolFun为函数容许误差 算法第一步根据输入变量数，将某些量设为缺省值( Simulated annealing algorithm of a function f (x) the minimum point, and l &lt = x &lt = u f is the unknown function, x0 as the initial point, l, u, respectively, lower and upper limits for the search interval, kmax is the maximum q iterations for the annealing factor, TolFun as a function of allowable error algorithm is the first step according to the number of input variables, set default values for certain amount of)

自己做的一个ZC序列的生存文件，希望大家喜欢(ZCSquence)

matlab图像图像处理，利用移位进行灰度值的变化，达到减小灰度值的效果(the matlab image change of image processing, by using shift grayscale value, to achieve the effect of reducing grayscale value)

对MATLAB环境下的迭代算法实现进行了讲述，对熟悉Matlab软件的人有帮助(The MATLAB environment iterative algorithm has been talk, for people who are familiar with Matlab software to help)

雷达信号的基本模型，高斯分布，几何分布，求信号的概率分布，概率密度函数，功率谱函数，自相关函数等等(The basic model of the radar signal, Gaussian distribution, geometric distribution, the probability distribution for the signal, probability density function, power spectrum, the autocorrelation function, and so)

This is a code in matlab for face recognition using PCA

说明：  本代码作为初学者，读取AVI电影（matlab能读的AVI电影难找），并提取关键祯，做差分(The code as a beginner, read AVI movie (matlab can read the AVI movie hard to find), and extract key frames, so differential)

说明：  电力能源预测，一个很好的模拟程序，可以供参考(electrical energy projections, a very good simulation program, to be available for reference)

该程序是结合john 的smo伪码，和网上其他程序写的。 特别是john 的smo伪码没写出来的部分，有点搞不懂，那一部分的a1old和a2old好像有点混乱。程序大部分能运行出来，有时很久没出来。(MATLAB SMO)

基于光正交码构造了一类新的不规则00c—LDPc码．新的LDPC码是准循环码，其编码复杂度与码长成 线性关系，具有编码复杂度低的特点，它所对应的双向图中没有四线循环．用和积译码算法对新的码字进行了仿 真，结果表明，与具有类似参数的随机码和规则OOc—LDPc码相比，当信道误码率为10。5时，译码增益分别为 0．3和0．15 dB．(Construct a new class of irregular the 00c-LDPc code based on optical orthogonal codes. LDPC codes are quasi-cyclic code, its complex coding with code length linear relationship, with low encoding complexity, the corresponding bidirectional Figure it in four-wire loop. Simulation with integrated decoding algorithm of the new code word, the results show that when the channel bit error rate, compared with the random codes with similar parameters and rules OOc-LDPc code decoding gain were 10.5 0.3 and 0.15 dB.)
