thank you i want to knows more about matlab thanl you advance

谱聚类 matlab 程序 　谱聚类是从图论中演化出来的算法，后来在聚类中得到了广泛的应用。它的主要思想是把所有的数据看做空间中的点，这些点之间可以用边连接起来。距离较远的两个点之间的边权重值较低，而距离较近的两个点之间的边权重值较高，通过对所有数据点组成的图进行切图，让切图后不同的子图间边权重和尽可能的低，而子图内的边权重和尽可能的高，从而达到聚类的目的。(Spectral clustering matlab program)

说明：  为了提高认知无线电中感知用户对授权用户(主用户) 的检测概率,提出一种新的基于循环 谱统计量的主用户信号检测算法. 该算法利用循环谱离散频域平滑方法,对信号的循环谱在循环频 率处建立合理的检测统计量,然后求解得到对应不同虚警概率的判决门限,以使感知用户能检测信 噪比更低的授权用户信号.(To increase the detection probability of sensing users for licenced users (primary signals) in the cognitive radio , it put s forward a new primary users signal method based on cyclic spect rum statis2 tics. By using discrete f requency smoothing of cyclic spect rum , this algorithm establishes the reason2 able detection statistics on the cyclic f requency of signal cyclic spect rum , then solves and obtains the decision threshold correspond to different false alarm probability , as a result , making the sensing users can detect licenced users signal under lower signal in noise ratio (SNR) .)
