说明：  实现大容量的图像信息隐藏，采用双随机置乱算法(Realize large-capacity image information hiding, using double-random scrambling algorithm)

说明：  传染病模型是指传染病的基本数学模型，研究传染病的传播速度、空间范围、传播途径、动力学机理等问题，以指导对传染病的有效的预防和控制。常见的传染病模型按照传染病类型分为SI、SIR、SIRS、SEIR模型等。由于2019年末出现的新冠肺炎有一定的潜伏期，与病人接触过的健康人并不马上患病，而是称为病原体的携带者，归为E类。(infectious disease model simulation)

计算信号的自相关矩阵的matlab程序，主要用于信号的实时分析。(Calculation of the signal autocorrelation matrix matlab program, mainly for real-time signal analysis.)

说明：  屎王nes资料，屎王nes资料，关于任天堂主机的(nes infomation，nes infomationnes infomation)

多天线系统中球形检测算法matlab源程序，包括仿真结果(Multi-antenna system sphere detection algorithm matlab source, including the simulation results)

Find a classification error for a given decision surface D and a given set of patterns and targets (Find a classification error for a given dec ision surface D and a given set of patterns and ta rgets)

bartle自功率谱密度分析，对于直接法的功率谱估计，当数据长度N太大时，谱曲线起伏加剧，若N太小，谱的分辨率又不好，因此需要改进。(Bartle since the power spectral density analysis, for the direct method of power spectrum estimation, when the data length N is too large, the spectrum curve of the ups and downs, if N is too small, the resolution of the spectrum and is not good, so need to improve.)

Methods to model communication channel

说明：  快速迭代收缩阈值算法，FISTA用一种更为聪明的办法选择序列{xk}，使得其基于梯度下降思想的迭代过程更加快速地趋近问题函数F(x)的最小值。FISTA的缺点是：Lipschitz常数L(f)不一定可知或者可计算。(Fast iterative contraction threshold algorithm, FISTA uses a more clever method to select the sequence{xk}, making its iterative process based on the gradient descent idea more quickly approach the minimum value of the problem function F(X). The disadvantage of FISTA is that the Lipschitz constant L(f) is not necessarily known or computable.)
