说明：  matlab编程，实现了基于内容的图像检索，基于颜色直方图和边缘直方图(Matlab programming, achieve a content-based image retrieval, based on the color histogram and the marginal histogram)

说明：  matlab kmeans 聚类算法 %X，样本（行为样本，列为属性) %idx，返回每个样本的类别，1，2，...,k %k,聚类数量(matlab kmeans clustering algorithm)

黄金分割法617 数学常用 函数逼近 建模运用 (Golden Section 617, the use of mathematical modeling commonly used approximation)

matlab gui设计学习手册第三章源码(matlab gui)

说明：  一本很適合新手入門的MATLAB工程書，希望大家可以學到東西(A Guide to MATLAB for Beginners)

主要是用c语言实现matlab中的fftshift函数的，(Mainly used c language matlab in fftshift function,)

课程设计做的PLL，里面有关线性和非线性的都有，大家可以(O 课程 设 计 的 PLL, 里面 Tang 关 Cave Cave性和非性的都 Tang, 大家可 Luk)

协作频谱感知虽然可提高系统的感知性能， 但随着感知节点数目的增加， 系统资源的占用越来越多， 系统传输效率下降． 分析了协作频谱感知方法的感知性能， 得到协作频谱感知的感知性能与感知节点数目和接 收信噪比之间的关系， 提出了一种新的次级用户节点的选择方法， 该方法有效保证了所选择节点的感知性能， 仿真验证了该算法的有效性和可靠性．(Although the cooperative spectrum sensing can improve the perceived performance of the system, but with the perception of the number of nodes increases, more and more system resources, the system transmission efficiency decreased. Cooperative spectrum sensing method of analysis of the perceived performance of collaborative spectrum sensing by the perception of performance and perception of the number of nodes and the relationship between the received SNR, a new secondary user node selection method, which effectively guarantee perceived performance of the selected node, the simulation proves the validity and reliability.)
