说明：  实现了基于mean-shift的图像检索，实现了比较两图像的相似度，选择最相近的图片(mean-shift)

This code is used in the course Digital Communications. It simulates 16QAM mode with different SNRs.

说明：  本算法采用遗传算法，用于辨识复杂洛伦兹系统参数。(Identification of Lorentz System Parameters)

带交叉因子的改进PSO算法，功能：求解多维无约束优化问题，特点：收敛性强，还可以加入变异算子(With cross-factor improved PSO algorithm, function: solving multi-dimensional unconstrained optimization problems, characterized by: strong convergence, mutation operator can also add)

这是一本通过MATLAB 环境下对数字信号进行处理的英文书籍。内容包括离散时间信号，离散傅里叶变换 时频分析等。是我很喜欢的一本书(This is a book by using MATLAB programming language for digital signal processing in English.and it includes Time-Frequency Analysis)

This is a program that calculate the criptosystem Diffic Hellman

Extended Mie Scatting Computatian By Matlab Code.密散射数值计算的Matlab代码，(Extended Mie Scatting Computatian By Matlab Code.)

uses the message signal X to modulate the carrier frequency Fc (Hz) and sample frequency Fs (Hz), where Fs > 2*Fc. FREQDEV (Hz) is the frequency deviation of the modulated signal.

matlab 关于association rule 的自己写的函数，有3个文件, association.m：h = association(m, i, j) i=>j, m是数据，h是support和confidence，该函数只适用于单个数据 ass_item: h=ass_itset(m, a, b) 同上，但是可用于多个数据（m为数组） assrule: h = assrule(m, threshold1, threshold2) 该函数用于classification， 得到规则，threshold1为要求的support,threshold2为要求的confidence，h 则为符合要求的规则及其support和confidence，前2列为规则，后2列为其support和confidence (matlab on the association rule to write functions, there are 3 files, association.m: h = association (m, i, j) i => j, m is the data, h is the support and confidence, this function applies only to a single Data ass_item: h = ass_itset (m, a, b) it is the same as above, but it can be used for multiple data (m can be matrix) assrule: h = assrule (m, threshold1, threshold2) the function used for classification,get the rules, threshold1 is the require of support, threshold2 is the required of confidence, h is the rules and their support and confidence, the former two columns as a rule, the latter two columns as one of its support and confidence)

最小二乘法的Matlab参数辨识程序,用于对模型的识别。(Least squares method of Matlab parameter identification program )
